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 circuit uses an operational that is not currently common. We found it in an old American...
This circuit uses two transistors to obtain low frequency sinusoidal signals. We found it in a...
This amplifier can be powered with voltages between 2 and 5 V with power up to 100 mW. The minimum...
