Power Supply Tester

This little circuit enables you to measure the so-called dynamic response of a DC power supply. A power MOSFET, T1, is used to switch the supply load on and off at a user selectable rate. The response of the supply to these fast load variations is displayed on an oscilloscope. The switching rate is selected[…]

Pulse Shaper

The diagram shows that how the four gates contained in a 4077 may be used to build a circuit that doubles the frequency of a signal applied to it. In other words, it generates a pulse for every edge of the input signal; the pulse width is determined by the internal delay of gates IC-1a[…]
