My idea on Dynamic Sampling

[Indian]

Regarding my final yr project i thought of a concept in sampling called dynamic sampling. Here i am going to change the sampling interval of the sampling pulse, for eg. let us take m(t) is the message signal now instead of sampling the signal with a ordinary pulse i am going to sample with a pulse width modulated pulse. through this i think we can achive information security. i dont know what will be its effect in frequency domain. i think i have explained clearly. i want you people to suggest on this project and tell me what will be its freq domain characteristics or whether the project is already existing
Thanks

hi
I see the same idea in numeric Integration in MATLAB function .The interval was vary, where input signal had fast change.
ODE(ordinary diff.. equation) function
I don't know about Ferq. domain charactristics.
