Two nonlinear stages are cascaded. If the input/output characteristic of each stage is approximated by a third-order polynomial, determine the P1dB of the cascade in terms of the P1dB of each stage.

See explanations for step by step pricedure to answer.

Explanation:

Given that;

Two nonlinear stages are cascaded. If the input/output characteristic of each stage is approximated by a third-order polynomial, determine the P1dB of the cascade in terms of the P1dB of each stage.

There:

Pn = K * T * G * B * F

where:

Pn: output noise power (in W)

K: Boltzmann's costant

T: Absolute temperature (in K)
