hi all
how to delay a continuous signal for a certain amount of time. i have a repeating sequence which needs to be delayed by 1 time unit in simulink after every 180 degrees.

use a "unit delay" block. set a sample time with an amount of time. after every 180 degrees? can you be more clear?

i have to compare a sine wave and triangular wave for pwm. the triangular needs to be phase shifted by half its time period every time sine wave is in its negative half cycle. and the triggering pulses generated must be simultaneous signals

use a "Transport Delay" block suggested by Govind and add a "switch" which will have 3 inputs
1- input 1 : your signal
2- input 3 : your delayed signal
3 -input 2 : your sine wave .
4- set a condition in your switch bloc
if the sine wave is positiv the output of your switch will be your original signal, and when the sine wave is negativ the output of your switch will be your delayed signal

You can use the Variable Time/Transport Delay blocks for introducing a delay in continuous signals. By 180 degrees, I'm guessing you mean a delay of one half of the period, which you should specify accordingly.

i tried transport delay but it is not working and i need a block from the continuous time segment.

Transport Delay is indeed meant for continuous signals.
