Peak Level Indicator by IC LM723

Circuit Peak Level Indicator by LM723
This the circuit checks signal sound level or Circuit Peak Level Indicator by LM723. Usual we often lead IC LM723 or UA723 come to use do , DC voltage Regulator. But for this circuit , build the circuit can check signal sound level with. When see the structure changes the integrated circuit. As a result participate of check volage with then bring apply for this not difficult work extremely. As a result request friends study the work has of the circuit follows a picture be lucky sir.
