Rutiner skrivna i Verilog har utvecklats för avkodning av en frekvensmodulerad signal givet ett Analog Devices AD9874-chip. Olika metoder för I/Q-demodulation har utvärderats och av dessa har CORDIC valts och implementerats i Verilog. Koden har till viss del testats på en IGLOO nano-FPGA men framförallt simulerats och verifierats i ModelSim. / Routines written in Verilog have been developed to perform I/Q-demodulation of a frequency modulated signal given valuesfrom a Analog Devices AD9874 chip. Different methods for I/Q-demodulation have been evaluated and among theseCORDIC has been chosen and implemented in Verilog. The code has to some extent been tested on a IGLOO nano FPGA but foremost been simulated and verified in ModelSim.
