Compute sum of RF signals
Use the Signal Combiner block to sum signals across each carrier frequency in the RF Blockset™ circuit envelope simulation environment. For an introduction to RF simulation, see the example, Simulate High Frequency Components
Select this option to internally ground and hide the negative terminals. Clear this to expose the negative terminals. By exposing these terminals, you can connect them to other parts of your model.
By default, this option is selected.
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 Weaver Receiver uses a Signal Combiner block as part of a realization of the Weaver receiver architecture.
