Up: Maximum Signal Level
Previous: Wide-band signal
In RF systems, the input signal of a filter may contain a blocker, which is
component at a fixed frequency which is by far the strongest component
of the input signal. Let the frequency of this component be
The maximum input signal level of the filter is then
The maximum output signal level for sinusoidal signals is
Vmax, in = .
If the blocker has been sufficiently suppressed, it does not play a role
in determining the maximum output signal level. In that case one of the
described above should be used to determine the maximum output signal level.
= | H(jωa)|2
To use this assumption on the input signal, specify
set: scale2 sfr;
and store the blocker frequency in the variable fr.
