srmdelay

Compute delay introduced by Sample-Rate Match block

    Description

    example

    delay = srmdelay(inputrates,inputlengths,outputrate,outputlength) returns delay in number of samples for the specified inputs. Use this function to compute the delay that will be introduced by the Sample-Rate Match block.

    example

    delay = srmdelay(inputrates,inputlengths,outputrate,outputlength,mode) returns delay in number of samples for the specified inputs. Use this function to compute the delay that will be introduced by the Sample-Rate Match block.

    Examples

    Resample a 5G signal at 7.68 MHz and an LTE signal at 3.84 MHz to a higher rate of 15.36 MHz.

    inpRates = [7.68 3.84]*1e6;
    inpLengths = [1e3 1e3];
    outRate = 15.36e6;
    outLength = 1e3;

    Determine delay incurred for a model configured for multitasking mode.

    d = srmdelay(inpRates,inpLengths,outRate,outLength)
    d = 2×1

    Resample a WLAN signal at 20 MHz and a 5g signal at 15.36 MHz to a higher rate of 30.72 MHz.

    inpRates = [20 15.36]*1e6;
    inpLengths = [2 1]*10;
    outRate = 30.72e6;
    outLength = 50;

    Determine delay incurred for a model configured for single-tasking mode.

    d = srmdelay(inpRates,inpLengths,outRate,outLength,"singletasking")
    d = 2×1

    Input Arguments

    collapse all

    Input sample rates in Hz, specified as a 2-element vector of positive values.

    Data Types: double

    Input lengths in samples, specified as a 2-element vector of positive integer values.

    Data Types: double

    Output sample rate in Hz, specified as a positive scalar.

    Data Types: double

    Output length in samples, specified as a positive integer.

    Data Types: double

    Tasking mode of the model, specified as either "multitasking" or "singletasking". The Treat each discrete rate as a separate task parameter of the Solver controls the mode of the model. For more information on the Treat each discrete rate as a separate task and Solver parameters, see Solver Pane (Simulink).

    Output Arguments

    collapse all

    Sample rate match delay in samples, returned as a 2-element column vector. The first element corresponds to the delay introduced in the first input and the second element corresponds to the delay introduced in the second input.
