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.
