Answer:
The components involved in the recovery of signal at the receiver in a digital communication system are:
b. Detector and sampler
The recovery of signal at the receiver in a digital communication system involves components such as the detector and sampler. The detector is responsible for detecting the binary signal, while the sampler captures discrete samples of the received signal.
In a digital communication system, the detector plays a crucial role in identifying the binary values from the received signal. It analyzes the signal and determines whether it represents a '0' or a '1'.
On the other hand, the sampler samples the received signal at regular intervals to obtain discrete samples. It captures the amplitude of the signal at specific time points, allowing for further processing and analysis.
These components, the detector and sampler, work together to recover the original binary signal from the received signal. The detector detects the binary values, while the sampler captures samples of the signal for processing.
