A op amp and transistors Q1 and Q2 exponential converter to generate an exponential gain control current, which is introduced into the recti...
Attenuator schematic
Two low voltage, low power zeners are used to control electronically the level of an audio signal. The attenuation range is from 6 to 58dB f...
Adjustable Attenuator for Oscilloscope
The input attenuator uses a commutating capacitor to cancel the input capacitance of the FET buffer (see DC-10 MHz amp schematic). The commu...
