This timer was designed mainly to switch off a portable radio after some time: in this way, one can fall asleep on the sand or on a hammock, resting assured that the receiver will switch off ...

The above circuit uses a 555 timer U1 in mono stable mode. If once push button is pressed, it drives pin2 of timer momentarily to ground that triggers the 555 to deliver a high output at pin 3 to ...

There are several ways to introduce an analog delay into a signal channel. If you have enough room in your product, an appropriate length of coax cable can be introduced. Inductor-capacitor delay ...

Negative group delay circuits represent an innovative frontier in electronic engineering, wherein the output signal appears to precede its input. This seemingly paradoxical behaviour is achieved ...
