TestBenchFracDelayStimulus - Specify input stimulus that test bench applies to Farrow filter fractional delay port

Settings

Note   This option applies only to Farrow filters.

Default: A constant value is obtained from the FracDelay property of the Farrow filter object, and applied to the fractional delay port.

'RandSweep'

A vector of values incrementally increasing over the range from 0 to 1. This stimulus signal has the same duration as the filter's input signal, but changes at a slower rate. Each fractional delay value obtained from the vector is held for 10% of the total duration of the input signal before the next value is obtained.

'RampSweep'

A vector of random values in the range from 0 to 1. This stimulus signal has the same duration as the filter's input signal, but changes at a slower rate. Each fractional delay value obtained from the vector is held for 10% of the total duration of the input signal before the next value is obtained.

Vector or function returning a vector

Define a vector as a workspace variable, store the stimulus signal in the vector, and pass in the vector name. Alternatively, pass in a call to any function that returns a vector.
