Wow the engineering world with your unique design: Design Ideas Submission Guide If the standard AND or OR logic elements are easily replaced by diode-resistive circuits, then the situation is much ...

For those cases a simpler approach”such as the circuit in Figure 1″ will do the job just as well. Figure 1: This circuit doubles the input frequency. The reference frequency in this circuit drives the ...

Since an XOR gate is a three-pin deal, with two inputs and one output ... with a few diodes. This circuit works by cheating, and works best with digital logic signals like what we’ve got.
