For a more analog MOSFET application, consider this simple AM modulator. Figure 4 MOSFET amplitude modulator. The circuit consists of an N-channel MOSFET, two resistors, and a Schottky diode. The ...

An AM transmitter is simple enough, ... built a basic circuit around a TA7642 AM amplifier ... of course, obvious: build your own AM transmitter, too. AM modulation isn’t that hard to ...

If you need only a few nonvolatile gates, consider using a component common in analog- and mixed-signal systems, the digital potentiometer, instead of a PAL, GAL, or CPLD, as described in “Nonvolatile ...

A crystal radio is a common enough science fair project, but the problem is, there isn’t much on anymore. The answer is, of course, obvious: build your own AM transmitter, too. AM modulation … ...

He tried the simple route and put a potentiometer in-line with the jacket. But he found that it got so hot, it began to smoke and melted his gloves. (The heater circuit draws upwards of 5 to 10 A.) ...

In a recent communication by Rakshit and Bhattacharyya1 it was pointed out that the conventional circuit of a three-phase system, with components selected for producing audio-frequency ...
