2.13 Decibels Engineers often measure the ratio of two power measurements in decibels, or dB. The equation for the ratio of two power measurements in decibels is (2-14) dB = 10 log10 P, where P2 is the power level being measured, and P, is some reference power level. (a) Assume that the reference power level P, is 1 milliwatt, and write a program that accepts an input power P2 and converts it into dB with respect to the 1 mW reference level. (Engineers have a special unit for dB power levels with respect to a 1 mW reference: dBm.) Use good programming practices in your program. (b) Write a program that creates a plot of power in watts versus power in dBm with respect to a 1 mW reference level. Create both a linear xy plot and a log-linear xy plot
