Detailed description

No detailed description exists yet for this component

Examples

Here is a simple example file for the Delay component.

FC6 Icon.png Delay

The DelayADC component is used to set the amount of delay that the component provides 0-2550 samples in steps of 10 samples.


The Input ADC component is used to pass a variable value into the DSP chain to allow the delay to be simulated.


Here is a picture showing the response of the delay component using the data recorder window.
