Multivibrator is a relaxation oscillator type. This circuit uses the RC network and the region contribute to the square wave output. Astabel multivibrator used in the TV receiver to control the electron beam on the picture tube. In this series of computers used to develop the pulse time. Astabil Multivibrator circuit HOW TO WORK A multibrator consists of two cross-coupled amplifier. The amplifier output is one connected to another amplifier wedding. Because each penguata reverse input signal, the combined effect of this is in the form of positive feedback. With the feedback posotif, the oscillator will always get the extra energy (regenerative) and produces a continuous output. The picture above shows the multivibrator circuit using 2 pieces of bipolar transistors with common emitter configuration. R1 and R2 provide bias voltage developed at the base of each transistor. Holding capacitor C1 to the base collector Q1 Q2. Q2 together with capacitor C2 to the base of Q1. Because of this cr...
