ANALOG-TO-DIGITAL CONVERSION
The task of the analog-to-digital converter (ADC) is the inverse of the
digitalto- analog converter: to convert an analog input signal into a
numerical digital value. The specifications for an ADC are similar to
those for a DA
APPLICATIONS OF DSP
MEASUREMENTS AND ANALYSIS
Digital signal processing traditionally has been very useful in the areas
of measurement and analysis in two different ways. One is to
precondition the measured signal by rejecting the disturbing noise and

COMPLEX NUMBERS
Now, on to the subject of complex numbers. We have stayed
away from this
subject until now simply because we did not want to confuse
things.
Initially, it is easy to think of signals as real valued. These
are what we
see when we look at a
CONTINUOUS FUNCTIONS VS.
DISCRETE SEQUENCES
When we look at a function like y ( t ) = sin(2 ft ) we
normally think of it as a
continuous function of t . If we were to graph the function, we
would compute
a reasonable number of points and then plot these p
DIGITAL-TO-ANALOG
CONVERSION
The task of the digital -to-analog converter (DAC) is to convert
a numerical, commonly binary digital value into an analog
output signal. The DAC is subject to many requirements, such
as offset, gain, linearity, monotonicity a
