Q. Explain Shunt-field control process?
Shunt-field control, armature-resistance control offers a constant-torque drive because both flux and, to a first approximation, allowable armature current remain constant as speed varies. The shunted-armature method is a variation of this control scheme. This is illustrated in Figure (a) as applied to a series motor, and in Figure (b) as applied to a shunt motor. Resistors R1 and R2 act as voltage dividers applying a reduced voltage to the armature. They offer greater flexibility in their adjustments to provide the desired performance.
Define Quantization Error? Quantization by its nature introduces errors. There are two major sources of errors. One is sampling, that just takes the amplitude of the signal at
