Abstract
A robust HiFi digital FM demodulation algorithm is discussed. Simulations demonstrate a performance surpassing analogue top-class receivers: a signal/noise ratio better than 90 dB for a sufficiently large carrier/noise ratio and a distortion level below 0.1% at 1 kHz modulation. For compact VLSI implementation, efficient shift-and-add-based CORDIC and IIR filter algorithms are used.Keywords
