1.	Which of the following is used when the number of channels is ten or less?(a) Two discriminators in series(b) Two discriminators in parallel(c) Series array of discriminators(d) Parallel array of discriminatorsI had been asked this question in a national level competition.The origin of the question is Pulse Height Analyser in division Radiochemical Techniques of Analytical Instrumentation
Answer» Correct OPTION is (d) PARALLEL ARRAY of discriminators Easy explanation: Parallel array of discriminators are used when the NUMBER of channels is ten or LESS. If the number is more than ten this is not preferred.
