Digital Transmission of AnalogData (Baseband Transmission):
• Analog voice data must be translated into a series of binary digits before ... an analogsignal is converted to its digital form.
• To obtain either form of pulse modulation we start with sampling.
Sampling is the process of taking samples (amplitude) of an analogsignal ... get back the original analogsignal we have to convert back the sampled signal to its unique analog
form. We could do it if we have taken enough samples of the original signal in the first place....

each DataView exposes a set of DataRow ... table to the DataView constructor.

Digital Signal Source:
The signal sources produce a series of “0”s (about –2.5 V) and “1”s (+2.5 V) at the data rate
set by the Master Clock. The time period of each bit is T = 1/fs. This signal ... detection process. This signal is useful in accurately measuring errors
in detected data due to a communications channel.
