Consider a low-pass signal with a bandwidth of 3 kHz. A linear delta modulation system, with step size ∆ = 0.1V, is used to process this signal at a sampling rate ten times the Nyquist rate. (a) Evaluate the maximum amplitude of a test sinusoidal signal of frequency 1 kHz which can be processed by the system without slope-overload distortion.

(b) For the specifications given in part (a), evaluate the output signal-to-noise ratio under (i) Pre-filtered, and

(ii) Post-filtered conditions.
