1.	To overcome the problem of representation of large values of gain, which of the following units was introduced?(a) Decibels(b) Joules(c) Pascals(d) FaradsI got this question in an interview for internship.Origin of the question is Active and Passive Devices in division Diode Circuit of Analog Circuits
Answer» CORRECT option is (a) Decibels To elaborate: Since 1dB=(1/10)log10(A2/A1) it is a logarithmic SCALE of REPRESENTATION and very large values can be expressed by smaller numbers. Decibels is a convenient UNIT of measurement for a VARIETY of applications.
