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 ...

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 ...

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

A word of advice: If you see an old direct satellite TV dish put out to the curb, grab it before the trash collector does. Like microwave ovens, satellite dishes are an e-waste wonderland, and just ...
