7. Given an RMS voltage signal of \( 5 \mathrm{~V} \). a. Calculate the signal power in \( \mathrm{dBW} \). b. Calculate the signal to noise ratio if \( -10 \mathrm{dBW} \) noise is added to the signal. 8. If the vertical axis maximum of the spectrum analyzer corresponds to \( 40 \mathrm{dBW} \) and the scale is \( 10 \mathrm{dBW} / \) division, find the amplitude of the \( 5^{5^{\text {th }}} \) harmonic in volts (i.e. convert \( \mathrm{dBW} \) to volts).
