The circuit in the figure uses two operational amplifiers: an LM101A and an LM102. Diodes admit equivalents and resistors do not have to be accurate. The power supply must be symmetrical.
This circuit uses old components, some of which can still be found easily. The circuit is from an...
In short wave receivers or in the recovery of signals from scratched discs this circuit can be...
The operating voltage of this circuit is 18 V, and the source current is 3.5 A. The circuit is...
