Image below “Sampled (discrete) signal” shows the sampled version of the signal above “Continuous              

signal”. The actual data consists only of the sampled points that you see as red dots in the diagram. The                    

lines in between the points are just interpolated. 

“Continuous signal”. But in comparison to image “Sampled (discrete) signal” we used a lower sample               

rate in this case. Because of the lower sample rate, we have fewer data points acquired and thus the                   

interpolated signal does not resemble the original signal as good as “Sampled (discrete) signal” does. 

The sampling rate (aka. sample rate, sampling frequency) deﬁnes the number of samples per second               

taken from the continuous signal to create the discrete signal. The unit for the sampling rate is hertz                  

(Hz) . The inverse of the sampling frequency is the sampling period or sampling interval, which is the                  

time between samples. 
