This conventional filter circuit is from American documentation from the 1990s. The operational amplifier admits an equivalent and the power supply must be symmetrical.
Found in American documentation from 1968, this circuit has an acute cut-off of the frequency to...
This low input impedance amplifier stage was found in a 1963 documentation. The circuit employs a...
We found this conventional sequencer configuration with the CMOS 4013 integrated circuit...
