Re: [Discuss-gnuradio] Change the frequency of signal periodical

[Marcus Müller]

Dear Atif,

please try to stay on-list (i.e. make sure address@hidden is in To: or CC:).

so, yeah, sounds like you want a source to generate these steps. In your case, what about using

vector source (vector being range(10,21,1) ) --> repeat (repeat factor = duration of each step / sampling rate) --> frequency mod (sensitivity accordingly)

I'd recommend you play around a bit!

Best regards,
Marcus

Dear muller i want to change the frequencies of signal source from defined values with a proper step size

like start 

frequency  starting value 10khz

step size                           1kHz 

frequency ending value  20khz 

This sequence automatically repeat itself

Dear Atif,
what does "periodically" mean in this context?

Feels like you actually rather have something like a "Signal Source [Square wave + offset]" -> Frequency Modulator

Best regards,
Marcus
