Detailed Solution
Download Solution PDFThe ability of a receiver to detect and amplify very weak signals is described by its sensitivity.
Concept:
1) Fidelity - This refers to the accuracy with which a signal is reproduced or copied. When applied to a radio receiver, a higher fidelity would mean that the output is a more accurate representation of the original signal.
2) Selectivity - This refers to the ability of a receiver to differentiate between multiple signals, particularly when they are close in frequency. Higher selectivity means the receiver is better at avoiding interference from signals at nearby frequencies.
3) Bandwidth - Bandwidth describes the range of frequencies over which a receiver can accept signals. A receiver with a wider bandwidth can accept a larger range of frequencies.
4) Sensitivity - This refers to the ability of a receiver to amplify weak signals so that they can be more easily processed. If a receiver is said to be sensitive, that means it is capable of detecting and amplifying weak signals.
