Learn how LM317 can be a power switch controller instead of a transistor. Try a simple power pulse generator circuit.
Imagine we want to detect the frequency. But we will use what methods or equipment is appropriate. Choose NE567 is Better. Why? The NE/SE567 tone and frequency decoder is a highly stablephase-locked loop with synchronous AM lock detection and poweroutput circuit. NE567 is good at driving a load whenever the input frequency within its detection … Read more
