Thank you very much, you have ended a great deal of frustration for what amounted to a simple problem. I hate knowing what you want to do but not knowing the correct terminology to search for the help. I doubt this class will teach me much about signals and systems in the end, but I think I'll...

I have inputed the following, I was given a signal and told to plot it in a time domain. The signal ECG is a data file and imported. N = 15000; fs = 250; t = linspace(0, 60, N); %signal = ecg data = ecg subplot (2,1,1); plot (t,ecg); title ('Time-Domain ECG') xlabel ('Time (s)') ylabel...

Yes homework, what relationship am I missing? I'm new to this area so any help is appreciated.

Q: A single sinusoidal signal is found in a large amount of noise. If the RMS value of the noise is 0.5 volts and the SNR is 10 dB, what is the RMS amplitude of the sinusoid? I've related the question to the following equation: SNR=20log(singal/noise)dB My answer is 1.58 volts, BUT I'm...
