Exercise 5.2
A signal a(t) band-limited te 3 kHz sampled at a rate 25% higher than the
Nyquist rate using PCM systerhe maximum acceptable error in the sample
amplitude (the maximu quantizaon error) is 0.25% of the amplitude range
R. The quantized samples binary coded.
a) Calculate the Nyquist samplng rate fN.
b) Calculate the actalsampling rate fs.
c) Determine the number of quantization levels L.
d) Determine the number of bits per sample b.
e) Calculate the bit rate R.
f) Calculate the minimum transmission bandwidth BPCM.
g) If 24 such signa are time-division multiplexed, determine the minimum
transmission bandwidth BTDM required to transmit the multiplexed signal.
