1.	What is the use of bypass capacitor?(a) to remove RF from non-RF circuits(b) to couple RF around an amplifier(c) acts as low pass filter(d) acts as high pass filterI had been asked this question during an internship interview.Enquiry is from SSB with Large Carrier topic in division Side Band Techniques of Analog Communications
Answer» The correct ANSWER is (a) to REMOVE RF from non-RF circuits To explain I would say: A bypass capacitor is generally used to dampen the AC or NOISE present at all frequencies. In COMMUNICATION, it is used to remove RF from non-RF circuits.
