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?

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.

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.
