Which of the following will increase or decrease the quality of the digital signal? a. Increasing the time between samples
b. Increasing the number of bits in each sample
c. Increasing the sampling frequency

decrease; increase; increase

Explanation:

Digital signals are simply referred to as time separated signals that can be generated when digital modulation is being used.

a. Increasing the time between samples

It should be noted that when there is increase in the time between samples, the accuracy of the digital signal becomes more defined. In order for the time between sample to be increased, the quality of the digital signal will have to be reduced.

b. Increasing the number of bits in each sample

There's increase in the level of quantization as the number of bits in every sample rises. The increase in the level of quantization reduces the noise which in turn, leads to a rise in the signal quality.

Therefore, increasing the number of bits in each sample increase the quality of the digital signals.

c. Increasing the sampling frequency.

There's reduction in time interval between the samples as the sampling frequency rises. Therefore, the increase in the sampling frequency increase the quality of the digital signals.
