Power Supplies,rpose. However, batteries eventually become discharged and then require recharging or replacing. Sometimes it is not feasible or desirable to use batteries due to the voltages required or the amount of current needed by the device. Therefore, another source of dc voltage is needed.

FET Amplifiers,ectromagnetic energy that is radiated from a radio or television transmitter tower reaches a receiving antenna it induces a voltage across the antenna. This voltage has an amplitude measured in millionths of a volt (µV). In order to get the desired sound from a radio speaker or picture on a televisi

BJT Amplifiers,s a majority of the current carriers are negative electrons while in .-type semiconductors the majority current carriers are positive holes. In the amplifying devices now under discussion, current flows through both .-type material and .-type material so current carriers of both polarities are invol

Radio and Television,/or electronic circuits that employ them. In this chapter a complete typical amplitude modulation (AM) radio receiver circuit will be studied in detail. This will be followed by a study of certain circuits used only in frequency modulation (FM) radio receivers. Selected circuits unique to television
