A transistor is connected in CE configuration with V_CC = 10V. The voltage drop across the 600Ω resistor in the collector circuit is 0.6 V. If α = 0.98, the base current is nearly.

A speech signal is sampled at a rate of 16 kHz and encoded into a PCM format using 16 bits per sample. The PCM data is transmitted through an AWGN baseband channel via 4-Level PAM the bandwidth required for transmission is

As shown in the figure, a negative feedback system has an amplifier of gain 200 with ±10% tolerance in the forward path, and an attenuator of value 9/200 in the feedback path. The overall system gain is approximately .
