Compute sum of RF signals
Use the Signal Combiner block to sum signals across each carrier frequency in the SimRF™ circuit envelope simulation environment. For an introduction to RF simulation, see the example, Simulate High Frequency Components
The example, Measuring Image Rejection Ratio in Receivers shows how to use a signal combiner to perform image rejection.
The example, Carrier to Interference Performance of a Weaver Receiver uses a Signal Combiner block as part of a realization of the Weaver receiver architecture.
