You have built an ECG system, and based on your knowledge of the heart, you have determined that the essential bandwidth is 300 Hz.You need to make a computationally efficient number of points for your DFT by forcing N to be a power of 2; however, you do not want to lose spectral resolution. Name three things you could change about your set-up and clearly explain (you do not need to explicitly calculate) the consequences each would have on the sampling frequency, sampling interval, frequency resolution, and total data acquired
