There are two common types of zero-crossing detection (ZCD) circuits: operational amplifiers and passive circuits comprising resistors, capacitors, etc. ZCD circuits are used for detection of zero voltage reference point in an AC signal or in a sinewave signal....
This short article describe simple circuit capable to convert a TTL/CMOS PMW signal to analog signal. The circuit can be used as extension shield for Arduino, with simple MCU or with TTL/CMOS signal generator. It is useful to produce audio signals...
