What is an electronic oscillator, and why is it essential in electronics engineering? An electronic oscillator is an electronic circuit that produces a periodic, oscillating electronic signal, such as sine, square, or triangular waves,...
Zener diodes serve as a reliable choice for achieving a constant reference voltage value in a circuit. It can maintain a constant voltage across it for a range of applied voltage values above the...
Analog amplifiers are fundamental components in the field of electronics engineering, serving the crucial role of boosting or magnifying electrical signals. These devices take in weak input signals and, through various electronic processes, increase...
The 555 timer integrated circuit (IC) has been a mainstay in the electronics world since its invention in 1971 by Hans Camenzind. Its popularity has endured for decades, and it continues to be widely...
A rectifier is a crucial electronic device that converts alternating current (AC) into direct current (DC). Whether you’re a budding engineer or just curious about electronics, this quiz will challenge your understanding of rectifiers...
DC power supplies that use AC supply as inputs are usually sourced from distribution lines that have voltage ratings of 110V or 230V and frequency of 60 or 50Hz. A rectifier circuit converts this...
Flyback diode In relay circuits, a flyback diode is a PN junction diode which is connected across the relay coil in reverse bias to the polarity of the supply voltage. It is connected to...
IC 4017 is a CMOS decade counter IC consists of a 5 stage Johnson counter with 10 decoded outputs that can count up to 10 decimals. It can be used for a variety of...
A DC filter circuit is a device that eliminates ripples in an input signal and allows DC to pass to the output. DC filters circuits are mainly used with the rectifier outputs to obtain...
A voltage level indicator is a circuit that can be used to indicate the voltage range of input supply. Usually, the circuit consists of a sequence of threshold points with the corresponding sequence of...
