This is a Digital logarithmic sweep signal generator circuit by use the average digital, It is designed to use together with the frequency generator by voltage controller. How it works From the circuit in figure 1 is the 14-bit binary counter circuit, that input is synced with the output of oscillator generator circuit. Then, the […]

We can use the schmitt trigger to generate the simple square wave. The duty factor of output waveform will be determined by the input waveform. But the threshold level is the importance. In Figure 1 will have the output while input waveform as Figure 2 cannot have output. Figure 1 Automatic duty factor controlled circuit […]
Here is the simple low noise filter circuit for any FSK signals that weak and have noise. This use few parts so easy and cheap. Fig 1: The schematic of this project As Figure 1 is the schematic diagram. This circuit include the low filter circuit through R1 and C2, the frequency cut off at […]
This wien bridge oscillator circuit which is normal,low distortion and can easily adjust the resonance frequency that depends on the pair of the resistors (R) and capacitors (C). Which we can calculate by the formula. F = 1/2 p RC In this circuit as Figure 1 the oscillator are based by the R that include […]
If a friend gets into trouble about the noise. Try out this circuit before, may like. It is Filter the Scratch and Rumble Noise Circuit. That make a friend feels annoyed very the character of the circuit filters this frequency , use , Resistor , and , Capacitors , or , RC Filter that often […]
