The Stereo Field is an intriguing box of synthesized tricks which contains mirrored stereo circuits that are manipulated through touch. When a player's skin touches plates on the upper surface, points ...

This simple stereo encoder circuit schematic is build with 2 IC MMC4066E and MMC4047 and one transistor BC547B. On IC1 2 and 3 pins is the audio output which is amplified by T1 (current amplification) ...

AT a meeting of the Students Section of the Institution of Electrical Engineers held on November 16, Mr. C. W. Eggleton read a paper on “The Frequency Stability of Tuned Circuits”. The author dealt ...

Since the days of pioneers like Marconi and Armstrong, radio has fascinated countless numbers of engineers. Wireless technology has evolved from the days of bulky, power-hungry vacuum tubes to today’s ...

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 ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...

The variable capacitor C1 and L1 will constitute the tank circuit which will produce the high frequency signal, the capacitor C1 is variable so that we can produce different frequency signal by ...
