EXAMPLE 4.4
In a binary symmetric communication (BSC) channel, the input bits transmitted over the channel
are either 0 or 1 with probabilities p and 1-p, respectively. Due to channel noise, errors are made.
As shown in Figure 4.4, the channel is assumed to be symmetric, which means the probability of
receiving 1 when 0 is transmitted is the same as the probability of receiving 0 when 1 is transmit-
ted. The conditional probabilities of error are assumed to be each e. Determine the average prob-
ability of error, also known as the bit error rate, as well as the a posteriori probabilities.
What is the bandwidth requirement in Hz for baseband binary transmission at 64 kbps, if the roll-off factor is 0.25?
EXAMPLE 6.4
Suppose the roll-off factor is 25% and the bandwidth of a baseband transmission system satisfying
the Nyquist criterion is 30 kHz. Determine the bit rate.

The torque of machine varies in a cyclic manner over a period of 2 revolutions. The torque rises from 650 N-m to 2200 N-m uniformly during 110° and remains constant for the following 270°. It then falls uniformly to 600 N-m during the next 100° and remains constant for the end cycle, the cycle being repeated thereafter. Determine the power required to drive the machine and percentage fluctuation in speed, if the driving torque applied to the shaft is constant and the mass of the flywheel is 180 kg with radius of gyration of 35 cm.
