Q1: MCQ1- class-B push pull power amplifier has maximum efficiency (25%, 50.5%, 78.4%,90%).2- The lowest distortion in output signal of power amplifier is obtained using class(A, B, AB, C)3- Impedance matching in tuned amplifier is used to improve (bandwidth, gain,input resistance, output resistance)4- Complementary class-B has an advantage over class-B push pull because of(higher efficiency, lower distortion, low power dissipation, save weight)5- The cross over distortion in power amplifiers occurs due to transistor non linear(transfer C/C, output C/C, input C/C, collector C/C).6- The d.c and a.c load lines in power amplifier are identical in (series fed load,transformer coupled load, push pull class-B, complementary class-B)7- The R-2R ladder type D/A converter is better than binary weighted resistor onebecause of its (high accuracy, low resistance spread, low power dissipation,high speed).8- Auto transformer is used in tuned amplifier to (transform low impedance oftransistor input, match to the load, tune to operating frequency, stabilize tunedamplifier).9- The dual slope A/D converter is popular because it is (fast converter, lowpower, low complexity, high resolution).10-The most important feature of flash type A/D converter is (high resolution,fast, low component spread, low power dissipation).
