Pulse generation with variable frequency

Hi everyone
I am trying to implement a pulse generator that generates pulses with variable frequency; let's say teh frequency is varying from 90kHz to 110 kHz; the pulse generation block only has fixed frequency.
Also, it is important to maintain the duty cycle 50%, which means giving 90to110 kHz to a sine block and comparing it to zero would not work (as far as I know by trying it)>
I would appreciate if anyone has any idea on this matter.

hello
it's a matter of how you implement the idea
here one solution
the attached model is a fixed step euler simulation
you have to initialize dt = 1e-7 in your workspace first
for the demo I have amplified the variable amount of the frequency
the graph below shows frequency, angle and output signal (as expected)

I am not sure to understand how you can have random pulse with fixed constant frequency

Need to main the duty ratio.. it may be +/- 1/3 of the desired frequency.. still i am trying to produce a pulse signal like that.
