Question about transfer function and amplitudes

Click For Summary
SUMMARY

The discussion centers on the application of transfer functions in signal processing, specifically regarding the multiplication of a transfer function by an input signal's amplitude. It is established that after substituting the frequency variable omega, multiplying the transfer function by the input signal's amplitude yields the output amplitude when converted to polar form. This method serves as an efficient shortcut for determining output amplitude without requiring the complete output function representation.

after substituting in your omega, can you multiply a transfer function by an input signal's amplitude, and expect the result to be the amplitude of the output? (once converted to polar)
This might be a shortcut way to find your amplitude when you don't really need a representation of the whole entire output function.
