variable delay block in simulink

i want to place a delay block which depicts a delay of the form d0+d1*Sin(2*pi*f*t). could anyone suggest any block? the blocks already available only alllow fixed delay.

What are d0 and d1? what is your input signal and what should be your output?

[Sinduri]

d0 and d1 are constants. The input is a gaussian monopulse and the output should be time delayed version of the input. But the delay has to be a variable delay of the type d0+d1*Sin(2*pi*f*t)

You can use the "Variable Fraction Delay" block from DSP System toolbox to implement this.

[Sinduri]

but it does not let you make a delay of the type mentioned above.

It has a delay input port. You need to compute d0+d1*Sin(2*pi*f*t) and pass as input to that block.
