Quantization noise: uniform quantization
nModel the quantized signal by
assuming ideal PAM sampling using the quantization error ek:
power
nQuantization
error is the difference of the reconstructed and the quantized
signal
nThe
final output is obtained by using the ideal LPF:
nAssuming
signal equal probable at all amplitude levels yields for quantization noise
average
