This cable tv amplifier circuit is a rf amplifier designed to be quickly installed between two coaxial cables. Both input and output impedances are compatible with 75 Ω cables. The main amplifier si ...

A simple op-amp circuit placed between a transformerless circuit with a ground tied to neutral and a circuit with an earth ground will eliminate the safety and noise problems associated with such ...

This hf circuit theory can be used to identify spurious resonances or oscillations in feedback amplifier and discrete transistor circuits, such as photodiode-input trans-resistance op-amps or emitter ...
