Time-quantized Frequency Modulation with Time Dispersive Codes for the Generation of Sigma-delta Modulation
Time quantization and noise shaping applied to linear frequency modulation (LFM) can form an alternative although unconventional means of generating 1-bit uniformly sampled code that is similar in structure to a feedback sigma-delta modulator (SDM). Fundamental insight into the SDM process and base-line coding spectrum emerges, where specifically linearity of signal conversion is studied and compared to that of linear pulse code modulation (LPCM). Time dispersive limiters both within and outside the noise shaper are investigated and their consequence on linearity explored. A noise averaging simulation reveals intrinsic distortion and noise modulation to be low when appropriate dither is used.
