The filter circuit of this main circuit will sent to through to the signal that middle frequency. At the same time is attenuated the others frequency into input signal to R1 through the base of emitter circuit as complementary form (T1/T2). And the feedback from the emitter lead of T1 and T2 through twin-T to […]

This dynamic compressors circuit that The reduction rate of the signal up to 20 dB at input between 100 mV to 10 volts. This circuit does not use external power. But used part of the input signal into a power supply. To reduce size of the signal. A part of the input signal is rectified […]
This Sawtooth wave generator circuit include of the frequency oscillator is controlled by current. Which can generate the sweep frequency in wide range. Suitable to be applied in the field of music equipment and a narrow pulse output. Also we are able to be a random circuit, and Hold. This circuit include of current variable […]
We can easily use FET and Crystal to generate the frequency and In particular, this circuit use very low voltage. It can operate at a supply voltage to 1.5 volts only and at crystal frequency 100 KHz to 10 MHz. The crystal is connected to between the drain and gate of FET-T1 BF256. It runs […]
This is simple crystal oscillators that provided square wave of 1MHz to 10MHz, Use an inverter gate IC and control frequencies with crystal. A oscillator or a frequency generator provide waveform out in various forms. For example : sine wave, Triangular waveform, Or square wave. The Frequency generator to control or out for a base […]
