Q. Explain Telephone hand set and it’s working ?
A standard telephone set is comprised of a transmitter, a receiver and electrical network for equalization, associated circuitry to control side tone levels and to regulate signal power, and necessary signalling circuitry. Essentially a telephone setis an apparatus which creates an exact likeness of sound waves with an electric current. Figure demonstrates functional block diagram of a telephone set. Essential components of a telephone set are ringer circuit, on/off hook circuit, equalizer circuit, hybrid circuit, speaker, microphone and a dialling circuit.
Q. Show how the conservation of power is satisfied by the circuit of Figure.
Using the LM741operational amplifier build a voltage amplifier with the voltage gain of |A V | = 500 v/v ± = 20%. Measure all necessary parameters of the amplifier (as per deliver
