This rapid response amplifier uses an integrated one that is not common today but can be implemented with modern equivalents. The circuit is from an 80's manufacturer documentation.
This circuit was obtained from a 1967 General Electric manual. The circuit uses components of the time,...
The capacitors on this circuit determine the frequency that this circuit can detect. We can adapt...
The frequency of this oscillator depends on the capacitors and typical values for the resistors are 10...
