The input power to a filter is 100 mW, and the output power is 5 mW. Calculate the attenuation, in decibels, offered by the filter.
Question 23.5: The input power to a filter is 100 mW, and the output power ...
N_{dB}=10 \log \frac{P_{out}}{P_{in}}
=10 \log \frac{5 mW}{100 mW}
=10 \times (-1.3)
= -13 dB
