A signal uniformly distributed in the interval (-5, 5) and bandlimited to 4 kHz, is sampled at a rate of 25% above the Nyquist rate and quantized. The quantization error must remain within 0.1% of the signal peak amplitude. The quantized sampled is encoded and transmitted using 4-ary pulses. The minimum number of 4-ary pulse required to encode each sample is N and B is the transmission bandwidth required to transmit the data by using 4-ary pulses satisfying Nyquist criterion with 25% roll-off. Then
