This circuit is an amplitude modulator circuit . T1 and T2 transistors are used to isolate the modulator section. Most of the low frequency signals. The optimal value is adjusted to about 500mV by the potentiometer Rp1. The low-frequency signal then passes through the isolation stage T3 to output a low-frequency modulated signal. The low frequency amplitude is adjusted by potentiometer Rp2.
