Q2] A-Discrete samples of an analog signal are uniformly quantized to PCM. If the maximum value of the analog sample is to be represented within 0.05% B- Show that the signal-to-quantization noise ratio in an n-bit binary PCM system, accuracy, find the minimum number of binary digits required per sample. where n is the number of bits uniquely assigned to each of the L quantization levels (L = 2n) is 1.76+6n dB with a sinusoidal analog signal input.
