# Maximum signal data rate

I have a frequency signal range from 25 Khz to 35 Khz. I know that the the minimum signal sampling to assure reconstruction of the signal from the samples is 70 Khz.

Would it be correct to assume that using the Nyquist's sampling criterion, the maximum data rate that the signal can carry for the 10 Khz bandwidth be 700 bits per second?

Do I multiply the samples per second (70) by bandwidth, which yields 700 or by 8 bits per sample?

• Minimum sample rate is 2*Fmax = 70kHz. Maximum baud rate (NOT data rate) is bandwidth/2 = 5kbaud. – markt Dec 13 '14 at 1:34
• I forgot to edit the minimum sampling rate. Updated... I'm confused on how to correctly get the data rate. – Rick Dec 13 '14 at 1:40
• Would I need to apply the following formula? D = 2 B log2K If so, I know B is the bandwidth, but not sure what K (signal levels) is. – Rick Dec 13 '14 at 1:47
