This is active high pass filter circuit for 327Hz frequency using LM741. It will use to build Harmonic at 3 of 130.81 frequency have the value at least. More than the frequency Fundamental 30 dB, for ...

Cypess' Dave Van Ess describes three problems associated with ac coupling a small signal riding on a large dc potential to a signal-conditioning amplifier, with solutions. Many sensors have a small ...

See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

An aerial filter is used to prevent unwanted signals from reaching your equipment, whilst allowing the wanted ones to pass through unaffected. Some filters may need to be installed before any ...
