The multivibrator is a common circuit that consists of an amplifier with both positive and negative feedback (Figure 1a). When the output is positive, the positive input terminal equals ½V+, and the ...

We must admit that we’ve been guilty of using a microcontroller to make two LEDs blink alternately in the past. It’s not the worst transgression, but it stems from our discomfort with analog circuits.

The HEF4047B is an integrated circuit containing a gatable astable multivibrator that is incorporated with logic techniques to allow positive or negative edge-triggered monostable multivibrator action ...
