### VDEL – Variable time delay

Block SymbolLicensing group: STANDARD

Function Description
The VDEL block delays the input signal u by the time defined by the input signal d. More precisely, the delay is given by rounding the input signal d to the nearest integer multiple of the block execution period ($n\cdot {T}_{S}$). A substitute value y0 is used until $n$ previous samples are available after the block initialization.

Inputs

 u Analog input of the block Double (F64) d Time delay [s] Double (F64)

Output

 y Delayed input signal Double (F64)

Parameter

 y0 Initial/substitute output value Double (F64) nmax Size of delay buffer (number of samples) for the time delay d. Used for internal memory allocation.  $↓$10 $↑$10000000 $\odot$1000 Long (I32)
