//Problem 41.01: The ratio of output power to input power in a system is
//(a)2 (b) 25 (c) 1000 and (d) 0.01
//Determine the power ratio in each case (i) in decibels and (ii) in nepers.

//initializing the variables:
//ratio of output power to input power

//calculation:
//power ratio in decibels

//power ratio in nepers
rpn1 = (log(rp1))/2
rpn2 = (log(rp2))/2
rpn3 = (log(rp3))/2
rpn4 = (log(rp4))/2
