Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

protecting circuits from electrostatic discharge (ESD), lightning, and other transient voltage events. Varactor Diodes, or varicap diodes, are used primarily in electronic tuning circuits. Their ...

Figure 2: Equivalent circuit to describe the transition capacitance In some applications, the transition capacitance is used and the corresponding device is known as a varicap (or varactor ) diode, ...

A selective input circuit improves antenna matching and immunity to interference from other strong signals. The preselector described here allows the use of up to four filters, tuned under software ...

In both the circuits described the r.f. oscillator is an astable multivibrator with a 1 0. 7 MHz ceramic filter in the coupling to determine the frequency of oscillation. Frequency modulation is ...

Then you have to replace the damaged fuse with a new one to make the connections again. Here in this circuit, Zener Diode and Bipolar Transistor are used for automatic overvoltage protection. It can ...

In very simple terms, a Rectifier is a circuit that converts an AC signal (Alternating Current) into a DC signal (Direct Current). It can be also said that a rectifier converts a bi-directional ...
