Abstract
A gain control or multiplier circuit in which an ac signal is applied through bipolar diodes having logarithmic response characteristics to the bases of bipolar transistors connected in series and having an output at their junction, the diodes being directly cross connected to the bases, and gain control signals of opposite polarities being applied to the bases, thereby providing a linear output from the transistors despite their non-linear response characteristics.
