Early radio receivers and record players nearly always had a knob marked “tone,” which was usually a crude low-pass filter with some form of severity adjustment. At best, these controls could ...

The circuit was constructed with the use of power audio amplifier LM380 in conjunction with the circuit that makes use of electronic soft switching and tone control. The circuit was constructed with ...

An international group of researchers has developed an electronic device that is said to effectively mitigate hotspots in PV modules. It uses two current comparators, two NPN transistors, and a ...

The diagram above is a typical PCB layout in Altium Circuitmaker software. The days of “electro” and “mechanical” being separate disciplines are long gone. Virtually all mechanical systems now come ...

While DSPs are the primary controllers in uninterruptible power supplies (UPS) with power-factor correction (PFC), ac generation and battery management, microcontrollers serve secondary functions for ...

QSPICE is an analog and mixed-signal simulator characterized by high simulation speed, accuracy and reliability. It is a new program and can be downloaded here. QSPICE is still in the demonstration ...
