FILTERS: Filters of some sort are essential to the operation of most electronic circuits. Filters and Signals: What Does a Filter Do? In circuit theory‚ a filter is an electrical network that alters the amplitude and/or phase characteristics of a signal with respect to frequency. Ideally‚ a filter will not add new frequencies to the input signal‚ nor will it change the component frequencies of that signal‚ but it will change the relative amplitudes of the various frequency components and/or

also had very poor comfort compared to modern types‚ usually having no padding and too often having excessive clamping force to the head. Their impedance varied; headphones used in telegraph and telephone work had an impedance of 75 ohms. Those used with early wireless radio had to be more sensitive and were made with more turns of finer wire; impedance of 1000 to 2000 ohms was common‚ which suited both crystal sets and triode receivers. In early powered radios‚ the headphone was part of the vacuum

Electrical Q&A Part-3 Questions and Answers related to Transformer: 1. What is a transformer and how does it work? * A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. It can be designed to “step up” or “step down” voltages and works on the magnetic induction principle. * A transformer has no moving parts and is a completely static solid state device‚ which insures‚ under normal operating conditions‚ a long and trouble-free

As compared with the common- base connection‚ it has higher input impedance and lower output impedance. A single power supply is easily used for biasing. In

#7 Questions & answers #8 Conclusion Objective In experiment 2 our main objective was to understand the analysis of resistors‚ inductors and capacitors in a sine wave circuit. we measured the impedance of the inductor and capacitor using a current sensing resistor. Inductive reactance is the opposition to the flow of current‚ and capacitive reactance is the opposition to the flow of charge. The tools we used for this experiment a pair of resistors
