Sweep Frequency Generator: Function, Features & Applications
Function & Features of a Sweep Frequency Generator A special type of signal generator which generates a sinusoidal output whose frequency is automatically varied or swept between two chosen frequencies is referred to as sweep frequency generator. One complete cycle of the frequency variation is termed as a sweep. The rate at which the frequency…

Frequency Synthesizer – Features, Operation & Applications
Frequency synthesis is a technique of producing a range of frequencies with crystal-controlled stability. A frequency synthesizer uses phase-locked loop (PLL) to generate output frequencies over a wide range. The typical range is from 1 MHz to 160 MHz. As illustrated in the block diagram above, the key components of the frequency synthesizer are: The…
