question

A decision has to be made whether a baseband signal should be modulated using delta modulation or pulse code modulation technique. If the signal- to- noise ratio, (S_o / N_q) where N_q = quantization noise and S_o = output signal power, during transmission for both mo-dulations should be at least 30 dB, determine the bandwidths ratio for PCM to DM (Hint: [(BW_pcm) / (BW_DM)] = [(f_mN) / (1 / 2\tau)] where N is the number of binary digits needed to assign individual binary code designation to the M quantization levels.
