We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train where the pulses are of equal duration. But this circuit detects the long ...

Compared to the simple diode needed to demodulate AM radio signals, the detector ... in the pulse train more easily detectable. As is his style, he walks us through a test circuit to prove that ...

An impulse detector circuit observes input pulses from an external sensor/source and converts into a processable output signal. Described here is a microcontroller-compatible event detector circuit ...

He’s built a finger-mounted pulse detector using a few simple components and an Arduino. This circuit uses a method known as photoplethysmography. As blood is pumped through your body ...
