i want to find out the specific reqency in signal like 50hz noise and band of 60-2000hz freq.

How can i do it?

If you have R2018a or later and the Signal Processing Toolbox, use the bandpass function to filter your signal.

to clean 50hz from the signal, can i use

bandstop(signal,[49 50],Fs); ??

I would use:

[signal_filtered, df] = bandstop(signal, [49 51], Fs);

You can then also use ‘df’ with filtfilt to filter other signals.
