I have a set of random data that samples the noise voltage at 20us. Right now I am plotting PSD in dB. How do I plot it with respect with dBV? The following is my code:
Fs=50000;
datasize=size(RANDOM);
numsample=datasize(1);
numsample=numsample;
FFTX=fft(RANDOM(:,2),numsample)...
Re: A DSP HW Problem
1 second of signal data gives you about 1hz resolution, but they are separated by only .75hz. Thus, they are not resolvable. Does that make sense?
Re: A DSP HW Problem
I thought about it again. I have a few questions:
1. We do not need to know the sampling rate in order to solve this probem (that’s what the problem says), but you did from calculating the sampling frequency. Isn’t sampling frequency = sampling rate?
2. Why did you pick...
Re: A DSP HW Problem
Can you be more specific on "you can calculate minimum sampling frequency which enables you to reslove two 0.75Hz seprated signals with 1second time interval samples?" I am not sure exactly how you do that... Thanks again!
A DSP HW Problem
In a recent article, a mathematician claimed that by using DFT to process 1 second of signal data it was possible to detect the presence of two sinusoids of roughly the same amplitude but separated by only 0.75 Hz. Is that really possible? Give a complete explanation of your...
