Signal Combiner

R2026b

Compute sum of RF signals

• 

Signal Combiner block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
RF Blockset / Circuit Envelope / Elements

Description

The Signal Combiner block sums signals across each carrier frequency in the circuit envelope simulation environment.

Examples

Measuring Image Rejection Ratio in Receivers

Calculate the image rejection ratio for high-side-injection in Weaver and Hartley receivers.

Carrier to Interference Performance of Weaver Receiver

A classic superheterodyne architecture filters images prior to frequency conversion. In contrast, image-reject receivers remove the images at the output without filtering but are sensitive to phase offsets.

Parameters

Ground and hide negative terminals — Ground RF circuit terminals

on (default) | off

Select this parameter to ground and hide the negative terminals. To expose the negative terminals, clear this parameter. By exposing these terminals, you can connect them to other parts of your model.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"simrfV2elements/Signal Combiner"

Example: add_block("simrfV2elements/Signal Combiner","myModel/myBlock",MakeNameUnique="on")
