Hi All I have created a single pulse which i want it to repeat every 2 seconds. How can i do that without using any of wave generator.

What is source of your single pulse ?
How it works ?

i have used 1 [constant] as an input for bitwise XOR and another input to bitwise XOR is same 1 [constant] but with 3ms delay. . this pulse has to be repeated every 2 seconds. .

I am not sure, but you can place your pulse source in a triggered subsystem to trigger it at some interval to repeat the pulse every 2 second.
Or use a while iterator block to repeat the output with some time delay arrangement.

i am facing similar problem, but here i used pulsetran function for generating pulse, if i multiply with sine signal with this pulse, i am getting something else. can i know how u have created this pulse? any code. Thanks in advance

This is just one way, but I've used it in the past to generate a pulse-sequence with 50% pulse-width:
----- -------------------------
| 0 |---------->| |
----- | |
Constant0 | Switch block |
------------------>|-| |-------------> Repeating Pulse
| ----- | Criteria: u2>=Threshold | |
| | 1 |---------->| Threshold=0.5 | |
| ----- | | |
| Constant1 ------------------------- |
| |
| ---------- |
-------------------------|Unit Delay|<--------------|
----------
You will need to tweak the sample times of the blocks to get a different pulse width - or alternately, use this generated pulse in place of your Constant block and XOR it with a delayed version of itself.

I am able to tweak pulse widths(3ms) for the above model, but what-about 2 secs period between 2 pulses. .
3ms 3ms
---- ----
| | | |
| |<-------- 2Secs-------->| |
----- ------------------------ --------------- - - -
0 0.003 2.003 2.006
This is the result i am trying for...

With my model, you will get a 50% pulse width. For something other than 50%, you should use my model as a source for your model (ie. instead of the Constant block, but with the XOR, etc.).
