Description

The Phase Shift block models an ideal phase shift in the circuit envelope environment. To learn how to use Phase Shift block to measure image rejection ratio in receiver, see Measuring Image Rejection Ratio in Receivers example.

Parameters

Phase shift — Phase shift angle

90 deg (default) | non-negative scalar integer

Phase shift angle, specified as a nonnegative scalar integer in degrees. The phase shift is applied to all nonzero simulation frequencies. For zero (DC) frequency, the shift is always zero.

Data Types: double

Model Examples

Measuring Image Rejection Ratio in Receivers

Use the RF Blockset™ Circuit Envelope library to calculate the image rejection ratio (IRR) for high-side-injection in Weaver and Hartley receivers. The Weaver receiver shows the effect of phase offset on IRR, and the Hartley receiver shows a similar effect for resistor variation.
