Question

In a binary PAM system, the clock that specifies the sampling of the correlator output is offset from the optimum sampling time by 10%.

If the signal pulse used is rectangular, determine the loss in SNR due to the mistiming.

Answer 1

In a binary PAM system, mistiming can result in a loss in Signal-to-Noise Ratio (SNR) due to the receiver sampling the signal at the wrong time. The loss in SNR can be calculated using a formula.

Step-by-step explanation:

In a binary PAM system, mistiming can result in a loss in Signal-to-Noise Ratio (SNR). The SNR is a measure of the signal's strength compared to the background noise. When the clock specifying the sampling time is offset from the optimum sampling time by 10%, the receiver samples the signal at the wrong time, leading to a degraded SNR.

The loss in SNR due to mistiming can be determined using the formula:

SNR_loss = 10 log(1/(1 + (2 * offset)^2))

Where offset is the fraction by which the sampling time is offset from the optimum sampling time.
