Useful Second Order Equations
In the following equations f refers to the fundamental frequency, and 2f refers to the second-order distortion component frequencies.
- OSOIdBm = ISOIdBm+GdB
- Pout,f,dBm = Pin,f,dBm - ISOIdBm + OSOIdBm
- Pout,2f,dBm = 2Pin,f,dBm - 2ISOIdBm + OSOIdBm
- Pin,2f,dBm = 2Pin,f,dBm - ISOIdBm
- Pout,2f,dBm = 2Pout,f,dBm - OSOIdBm
is the difference in power between the fundamental output and the output of the second-order components, as shown on the figure to the right.

Famous quotes containing the word order:
“The comic spirit is given to us in order that we may analyze, weigh, and clarify things in us which nettle us, or which we are outgrowing, or trying to reshape.”
—Thornton Wilder (1897–1975)
