Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...
Switching algebra is easily visualized using switches since there are only two values: on and off, or true and false. In digital systems we represent these as 1 and 0, respectively. There are only two ...
If you simulate circuits that include not only analog, but also digital or switching/PWM aspects, then you know that traditional “AC” or frequency-domain analysis cannot be used for these designs.
