A Note on Decibels unit. Ratio of output power to input power to a subcircuit
is usually given in units of decibel. The formula for conversion to decibel is
given in Page 15 of text book (problem 1.26) as well as in page 596. It is
PR (db) = 10 log (Po/Pi)
Since power in a load resistor scales as square of voltage, conversion formula
to decibel can be written in terms of voltages as
PR (db) = 20 log (Vo/Vi)
Bel and Decibel units (log of power ratios instead of power ratios themselves)
are used because human ear "hears" the sound in a logarithmic fashion, i.e., a
sound that appears to be twice as loud is 10 times higher in power and three
times as loud is 100 times power!
