Q. What do you mean by Companding?
In order to lower the crest factor of a waveform, so as to produce better performance, a process known as companding is used. It works like a compressor which progressively compresses the larger amplitudes of a message when it is passed through a nonlinear network. The inverse operation in the receiver is known as an expandor, when it restores the original message. Figure 15.3.4 illustrates a typical set of input-output characteristics for a formof compandor.One can see that the action of the compressor is to increase the rms-signal value for a given peak magnitude.
A 3 phase, 6 pole induction motor is rated at 400hz, 150v, 10h.p., 3% slip at rated power output. The windage and friction loss is 200w at rated speed. With the motor operating at

Q. A charge variation with time is given in Figure. Draw the corresponding current variation with time.
Based on Figure, using star-delta transformation, calculate the current flow and voltage drops at 6kΩ resistor.
On running the simulation, a data display will automatically open, similar to that shown in figure. The red circle is the source mismatch stability curve. This will give an indicat
