In a superheterodyne radio, a local oscillator is an electronic circuit that generates a frequency based on the desired channel. The output of the oscillator is the channel frequency typically added ...

Side-stepping traditional laser local oscillator down-conversion techniques, Australian engineers are using acoustic interactions to retrieve frequency and phase information from Gbit/s modulated ...

The ADL5812 uses revolutionary new broadband, square wave limiting, local oscillator (LO) amplifiers to achieve an unprecedented radio frequency (RF) bandwidth of 700 MHz to 2800 MHz. Unlike ...

A greatly simplified block diagram of an atomic frequency standard (also called an atomic clock) is shown in Figure 2.1. This consists of an atomic resonator, a local oscillator, and additional ...

Parametric oscillators are a driven harmonic oscillator that based on nonlinear process in a resonant cavity, which are widely used in various areas of physics. In the past, parametric oscillators ...

Digital receivers have revolutionized electronic systems for a variety of applications including communications, data acquisition, and signal processing. This series shows how digital receivers, the ...
