DSP EXAM 2006

(d) Explain the term ‘quantisation noise’ A DSP system, with a 16-bit uniformly quantising analogue-to-digital converter and a sampling rate of 20 kHz, is used to process analogue signals band-limited to the frequency range 0 Hz to 5 kHz. Estimate the maximum achievable signal-to-quantisation noise ratio (SQNR) for sinusoidal input signals, and state what assumptions it is reasonable to ... ................
