Power Measurement of Complex Signal However, a 2V pp sinewave dissipates 10dBm of power in a 50 ohm resistor, and in a system that has a characteristic impedance of 50 ohms, Learn the basics. Get a copy of Oppenheim Shaffer's Signal Processing. If you crack it open and you don't understand the underlying math, learn that math. The vast utility of Fourier methods in signal processing beyond intuition is due to several powerful properties of complex sinusoids. Hence, due to the differentiation and time delay properties, the output of an LTI system in response to a complex sinusoid input is a complex sinusoid of the same frequency. 1 What is a Signal We are all immersed in a sea of signals.
