Although the ubiquitous LM386 IC was designed to be used as an audio amplifier, it has a number of undocumented characteristics that can be exploited to create simple radio receiver circuits that ...

SUNY Polytechnic Institute in Marcy is opening four new research centers in the fields of intelligent manufacturing, ...

TDA integrated circuits series are very well appreciated and used in amplifier ... TDA2005 is a class B dual audio power amplifier specifically designed for car radio applications. Its high current ...

Rearranging the capacitors so that the feedback curve is reversed creates a high-pass filter as shown in Fig. 5. A downside of these circuits is the progressive shifting in phase of the signals going ...

Even in today’s digital, IT-intensive radio plant, there is still a need to design and build one-of-a-kind electronic circuits. Simple devices such as digital tone generators and small distribution ...

[kodera2t] takes us through a few circuits built with these tubes, from a simple subminiature vacuum tube radio to a more complex reflex radio. Taking a walk through this history is an interesting ...

Circuits printed on polymers are currently less ... Gadgets such as cell phones could one day use residual radio signal to supplement their own batteries, but the amounts of energy harvested ...
