| + | The Voltage Controlled Delay block adds a variable amount of sample delay to the input signal. Unlike the Delay block which adds a fixed amount designated in the control, the VCD allows for a data input to control the amount of delay that is applied to the input signal. | ||

| + | The **Max** setting still corresponds to the maximum amount of delay that is reserved for the input signal. Thus any delay values designated by the data control pin, must be between 0 samples and the value in the **Max** drop-down. There is more detailed information about the data memory reserved by the **Max** drop-down in the last section below. | ||

| + | In the example above, the VCD algorithm is grown in order to support 2 separate delay taps to the input signal. The first output pin of the VCD is connected to channel 0 - Output1. Output1 is receiving a delayed version of the input signal by 480 samples. This is a fixed amount of delay designated by the DC input block which has the value 480 in integer format (28.0). | ||
| + | |||
| + | The second output pin of the VCD is connected to channel 1 - Output2. Output2 is receiving a variable delayed version of the input signal. This is accomplished by using a low-frequency oscillator (LFO). The rate of the LFO (0.1Hz) determines how quickly the sweep of delay will be using a [[resources: | ||
