The video circuit illustrated in Figure 1 combines an audio-subcarrier notch filter and group-delay equalization as required by the ITU-470 standard. It also includes an amplitude-adjustment ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

The circuit exemplifies the use of ZN414 IC to produce a handy AM radio receiver. ZN414 IC– a composition of transistor tuned radio frequency (TRF) circuit packaged in a 3-pin TO-92 plastic package ...
