This circuit transforms 0 and 6 V signals into -4 to 10 V signals and can be used in a shield. The circuit uses transistors that are still common today.
This circuit compensates for losses in pre-amplified audio or tone control stages. The circuit can use...
Found in the Encyclopedia of Electronic Circuits volume 5 from 1995, this circuit uses a...
This is a bridge for the measurement of low value resistances and high values too. The circuit...
