Yes, you can. But an additional external circuit is usually necessary. Depending on what exactly you want to check (frequency, amplitude, peak value, rms value, distortion, etc.), this circuit is more or less complex.

Thank you
i want to check Frequency & amplitude
Frequency can be check by Zero crossing Detector comparator and input capture of timer.
What about amplitude ,Peakvalue?
