This filter has the components calculated for the frequency of 1 kHz but can be changed. The input resistor can be 100k and the source symmetrical. Any operational amplifier can be used.
This circuit is more sensitive than the previous one (CB4118E) for using a full wave detector. The...
These circuits use loads of 50 ohms to allow the use of a voltmeter in evaluating the output of a...
The circuit shown was found in Intersil documentation from the 90s. The formula allows to...
