This precision signal rectifier was obtained in an American technical documentation from 1975. The operational amplifiers can be 741 and the power must be supplied from a symmetrical source.
This astable multivibrator configuration causes two LEDs to alternately flash at a frequency...
Found in documentation from the 1990s, this circuit modulates the pulse width without changing its...
Taking advantage of the comparator setting, we can use the Norton amplifier as an over temperature...
