Explain how to recognize amplitudes in order for an analog signal to be correctly reconstructed in its original shape at the receiver side
What will be an ideal response?
To recognize these amplitudes, we need to hold the amplitude of each impulse signal constant during the sampling period after generating a specific impulse. Employing a capacitor at the output of a sampling circuit will help us hold each sample for a sampling period of time. There are many encoding methods in data communication. Return to Zero (RZ) and Not Return to Zero (NRZ) are two basic encoding methods. The sampled signal and sample and hold signal are representations of these two encoding methods respectively.
