Hi all
I'm a begginer in digital signal processing,I have a signal that varies in 10Mhz to 30Mhz range and has almost very noises and I want to measure its dominant frequency component,I think that it can be done by taking FFT,but it may works slower than I need.
what's your suggestions?
(and a TMS320C6713-DSP is accessible):?:

Do you have access to the analog electrical signal? Suppose you use a bandpass filter to remove everything not within your desired frequency range?

With less noise you might have an easier time detecting positive/negative peaks, or up/down transitions.
