4 channel audio splitter / Audio Distribution Amplifier 4558

The three channel output distribution amplifier uses 4558. The first stage is resistor coupled with a 33k.… Each output stage independently drives an amplifier through the 50 µF output capacitor to the 4k7 kΩ load resistor.

Making Frequency Modulation circuit

In this case the frequency of the oscillator is determined by the values of the capacitor and inductor: C and L. Notice that I have now added a diode and another capacitor 10C (10 times bigger than C). The oscillations across the ends of L are a sinewave, varying above and below the Gnd (battery […]
