This is Simple Tone Oscillator Generator. It is use transistor 2N2222 and 2N2907 be main part. By control tone sound with R2 – 50K and use 8ohm size. Detail other loudspeakers have a few , request friends see in the circuit please yes. Related Links tone audio circuit More Circuit by transistor 2N2222 Oscillator generator [...]
This filter allows you to remove frequency band from a signal. In the example below, we’ll design a 50Hz notch filter. This allows us to remove the 50Hz hum picked up by, say, a microphone cord. Of course, it can be easily designed for 60Hz as well. Related Links More Circuit Filter More Circuit Bandpass [...]
The simple Function generator two waveform, It produces triangle and square waves from 1Hz up to 1MHz. The Amplitude, offset and duty cycle are adjustable to offer wide range of generated signals. The important part of the circuit is LM566 or NE566. I used R2 controls Frequency output. The power supply voltage is 9V to [...]
