Relationship between Epoch Length and Frequency

Hi, I’m writing to ask for help with choosing epoch lengths when analyzing data.

I have a sampling rate of 200Hz, the number of mini-epochs is 30 and the length is 1 second.
Will I have a problem analyzing a signal with a frequency of 1 Hz?

In my opinion, it meets the Nyquist frequency criterion,
I think it’s enough if one epoch contains all the components of 1 Hz.
However, I’m wondering if I’ll run into problems with this analysis compared to a mini-epoch with a length of 2 seconds x 15.

Do I need to have at least 2 waves of frequency components?
Or does it not matter because I am using all epochs in the analysis anyway?
I would like to get your opinion on which one is more accurate or if both are okay.

I’d love to hear from those with more experience.
Thanks.

Late response, and not a concrete answer, but for these types of questions, I recommend browsing the educational materials of Mike X Cohen, who has great free courses on EEG time frequency analysis basics.
