Hi, I'm working on energy detector spectrum sensing and I want to know the relation between the time-bandwidth product and number of samples. From what I have read till now my understanding is that time-bandwidth product is TW, where, T is the observation time and W is the bandwidth, which can be rewritten as N Ts Fs, where N is the number of samples, Ts is the sampling time and Fs is the sampling frequency. That means the time-bandwidth product is simply the number of the samples is that true or wrong
Thanks in advance
Can you be more clear please, and maybe we will try to help you by any way.
Hi Dr, I hope you're fine.
In the equation you stated, W is supposed to be equal to Fs which is not true in most cases. According to Nyquist criteria, Fs should be twice W. In this way, T is not equal to N.
