Digital Volume Controller Circuit
This Digital Volume Controller Circuit talks about special type of electronic volume control, which does not uses normal knob but it uses an electronic parts. Also, normal volume knob uses resistor but this one uses small computer chip to control sound level; as it gives more function and also with more correctly. Circuit Working: Parts […]
Variable Notch Filter Circuit
This Variable Notch Filter Circuit have a special filter, which can change to remove some sound frequency. Also, we can adjust it how we need and that make it useful; as this filter is also call band reject filter or band stop filter. Furthermore, it mostly removes or make small certain noise in one range, […]
