M-Net decoder production : a technical analysisGreen, David Robert January 1989 (has links)
Thesis (Masters Diploma (Technology))--Cape Technikon, Cape Town, 1989 / The document initially describes the operation of the
decoder and the production system. Thereafter actual
engineering problems are stated and their solutions discussed.
The project involves the accurate identification of problem
areas on the production line and the systematic solving for
each case. Subjects include static electricity pretesting
and automatic insertion machine defects.
Analysis of these problems provides one with a better
perspective towards the production line and its inherent
problems. Results and solutions are presented photographically
as well as tabulated in the annexure. In some
cases, such as defect classification, deductions were
concluded that were very different from those initially expected.

Modular approach to the development of a two-way radio receiver systemKellerman, Valpre Cecilia 12 1900 (has links)
Thesis (MScIng)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: The preliminary development of a FM radio receiver module is discussed. An existing narrowband
system operating between 48MHz and 50MHz will be replaced. Digital components were
investigated, compared and used with analogue techniques to build a more flexible two-way radio
receiver system. A direct digital synthesizer was considered as a replacement for the current
synthesized phased lock loop local oscillator and much attention was given to the local oscillator
and mixer design, characteristics and measurement procedures.
A detailed study of receiver systems was undertaken to determine the specifications needed for
every receiver component to achieve satisfactory receiver performance in the end. Receiver
characteristics as well as receiver measurement procedures are defined. A software tool was
developed to aid the design process, establishing computationally whether the receiver
specifications are met prior to the final design.
The complete design process, from fundamental specifications through to the developed final
receiver module is discussed. A modular design approach was used to guarantee easy
manufacturing, substitution and testing. This approach comprises the break-down of the receiver
into well defined components that are each matched to 50O. The separate components of the
system were designed, measured and characterized to make it possible to replace only a single
component instead of the entire system when a part becomes redundant. / AFRIKAANSE OPSOMMING: Die grondslag vir die ontwikkeling van ‘n FM radio ontvanger module word in hierdie dokument
gelê. ‘n Bestaande noubandstelsel wat tussen 48MHz and 50MHz ontvang word vervang deur
hierdie nuwe stelsel wat aangewend sal kan word in die bestaande tweerigtingradio se omhulsel.
Digitale komponente is ondersoek, vergelyk en gebruik saam met analoogtegnieke om ‘n meer
buigsame radiostelsel te bewerkstellig. ‘n Direkte digitale sintitiseerder is oorweeg as ‘n
vervanging vir die huidige fasesluitlus ossillator met heelwat klem op die oscillator-en
mengerontwerp, komponent spesifikasies en metingsprosedures.
‘n Diepgaande studie van ontvangerstelsels is gedoen om te bepaal wat die tipiese spesifikasies
vir elke ontvangerstadium is, sodat die finale ontvanger se spesifikasies behaal kan word.
Ontvanger eienskappe en meetprosedures word volledig gedefinieer. ‘n Sagtewareprogram is
ontwikkel om die ontvanger-ontwerpsproses te vergemaklik deur vooraf te kan vasstel watter
ontvangerspesifikasies bereik sal kan word al dan nie.
Die volledige ontwerpsproses, vanaf fundamentele spesifikasies tot by die finale ontvanger word
omskryf. ‘n Modulere-ontwerp prosedure is gebruik ter versekering van die maklike vervaardiging,
vervanging en toetsing van elke komponent. Die radio is tydens ontwerp opgebreek in
boublokkies wat elkeen aangepas word na 50O. Elke aparte boublokkie van die ontvangerstelsel
is afsonderlik ontwerp, gemeet en volledig gespesifiseer om dit moontlik te maak om slegs een
komponent te vervang in plaas van die hele stelsel wanneer ‘n enkele komponent nie meer
beskikbaar is nie.

Radio frequency and microwave design methods for mobile communicationsBanciu, Marian Gabriel, Electrical Engineering & Telecommunications, Faculty of Engineering, UNSW January 2003 (has links)
The Global System for Mobile communications (GSM), which covers 54% of the world's mobile market, evolved into the General Packet Radio Service (GPRS). The thesis addresses interference suppression using new radio frequency (RF) and microwave design methods for GSM and GPRS. The overall outcome is interference reduction and enhanced network capacity, leading to superior quality of service (QoS) for wider area coverage. The main results can be summarized as follows * Design, manufacturing and characterisation measurements of new compact filters for GSM and GPRS base stations in order to reduce the out-of-band interference. It is shown that filters with novel microstrip resonators - dual mode filters and cross coupled filters - provide both a high degree of miniaturisation and narrow bandwidth. * Development of a new 3-D Finite-Difference Time-Domain (FDTD) design method for new microstrip filters. A non-homogeneous Perfectly Matched Layer (NH-PML) was implemented for Absorbing Boundary Conditions (ABC) to increase the accuracy of the FDTD method. Signal estimation techniques were developed to speed up FDTD computations. A novel design method based on neural networks (NN) and FDTD was implemented to reduce the total design time. * Investigation of High Temperature Superconductors (HTS) thin film resonators and antennas at microwave frequencies. High Q-factor HTS devices considerably enhance both the front-ends sensitivity and selectivity of wireless receivers. * Design, manufacturing and testing of radio frequency (RF) electronics for 16 elements GSM and GPRS Smart Antenna for multipath fading mitigation and for in-band interference including co-channel interference (CCI) suppression.

The design of delta-sigma modulators for multi-standard RF receiversLiu, Mingliang 09 June 2003 (has links)
The transition from second-generation (2G) to third-generation (3G) wireless
cellular and cordless telephone systems requires multi-standard adaptability in
a single RF receiver equipment. An important answer to this request is the use of
Delta-Sigma modulators for IF-to-baseband conversion, which will satisfy the dynamic
range requirements for digital signal processing, and at the same time, add
adaptability and programmability to the characteristics of a RF receiver.
This thesis addresses the issues of designing a Delta-Sigma modulator for a
multi-standard wireless receiver. A single-loop third-order modulator topology suitable
for low power and high integration multi-standard receiver design is proposed.
The trade-offs in the modulator design are also presented and explained. The modulator,
which has been implemented as a part of a monolithic receiver chip, will be
fabricated in a standard 0.35-��m CMOS process. The post-layout simulation results
have verified the outcomes of system analysis. / Graduation date: 2004
