Usually we used the IC – NE567 is only tone decoder circuit. But friends believe or not. We bring it to a frequency generator circuits as well. The band has twin frequencies are 1.6Khz and 4kHz. -Both on the square waveform signal, - and It has level amplitude in voltage output maximum as same as [...]
