1.	What is pre-amplification?(a) reducing the magnitude of a signal(b) making the magnitude of a signal zero(c) reducing the noise(d) boosting the signalI got this question in my homework.Origin of the question is Single Channel Data Acquisition System topic in section Data Acquisition System of Electrical Measurements
Answer» Correct CHOICE is (d) boosting the SIGNAL Explanation: To match the input needs, the level of an input signal is BOOSTED. This is done as the magnitude of the input signal is sometimes very LOW. This is known as pre-amplification.
