After pre-amplification the signals are fed into ____________(a) an electronic switch(b) a signal generator(c) a rectifier(d) a regulatorI got this question by my college director while I was bunking the class.Origin of the question is Dual Trace Oscilloscope topic in chapter Oscilloscopes of Electrical Measurements
Answer» The correct choice is (a) an electronic switch To elaborate: In a Dual Trace OSCILLOSCOPE, after the pre amplification PROCESS is done, the signals are fed into an electronic switch. The switch passes one channel at a TIME through the delay LINE.
