Found in a 1965 Electronic Design, this circuit divides the frequency of a cascaded signal using unijunction transistors. The bipolar transistor supports an equivalent. The shock is 470 mH.
Based on 74HC digital circuits, this circuit generates signals in three phases. The frequency...
We found this circuit in a 1982 publication. The circuit can still be easily assembled, but for...
We found this circuit in a Motorola manual. The circuit employs operationals that are uncommon today...
