Therefore we can express all the image frequencies as for any integer N (with being the actual signal frequency).

The signal frequency was changed less often.

When the circuit size is comparable to a wavelength of the relevant signal frequency, a more sophisticated approach must be used.

Its purpose is to allow a range of signal frequencies to pass, but to block others.

The change in signal frequency is identified by the software and appropriate action taken.

This impedance may vary in value with signal frequency and amplitude.

The receiving side will interpret the signal frequencies, waveforms, and delay, etc.

Bias tees are designed to operate over a range of signal frequencies.

The deleterious effects of an imperfect transmission line become more noticeable at higher signal frequencies.

They were pinned to the wall, as part of a list of dedicated signal frequencies.
