Which of the following is the function of the discriminator?(a) Reject

1.	Which of the following is the function of the discriminator?(a) Rejects signals below a certain voltage(b) Rejects signals above a certain voltage(c) Rejects signal in a range alone(d) Filters noise aloneI got this question by my school principal while I was bunking the class.I need to ask this question from Pulse Height Analyser in portion Radiochemical Techniques of Analytical Instrumentation
Answer» Correct OPTION is (a) Rejects signals below a CERTAIN voltage To EXPLAIN I would say: The discriminator can be set to reject signals below a certain voltage. This is required for EXCLUDING scattered radiation and noise.
