Introduction to Local Oscillators Local oscillators play a crucial role in modern electronic circuits, especially within the domain of radio frequency (RF) applications. Fundamentally, a local oscillator is an electronic circuit that generates a stable frequency signal. This output frequency can then mix with an input signal, resulting in the production of a new frequency. […]
