The term mixed signal processing implies that both analog and digital processing is done as part of the system. The system may be implemented in the form of a printed circuit board or a single integrated circuit chip. In the context of this broad definition, ADCs and DACs are considered to be mixed signal processors, since both analog and digital functions are implemented in each. Recent advances in Very Large Scale Integration (VLSI) processing technology allow complex digital processing as well as analog processing to be performed on the same chip. The very nature of DSP itself implies that these functions can be performed in real-time.
the choice of techniques is clear; in others, there is no clear cut
choice, and second-order considerations may be used to make
the final decision.
With respect to DSP, the factor that distinguishes it from
processors, performing such functions as multiplication (gain),
isolation (instrumentation amplifiers and isolation amplifiers),

detection in the presence of noise (high common-mode instrumentation amplifiers etc.), dynamic range compression (log amps, LOGDACs, and programmable gain amplifiers), and filtering (both passive and active). Several methods of accomplishing signal processing are shown in Figure 9.5. The top portion of the figure shows the purely analog approach. The latter parts of the figure show the DSP approach. Note that once the decision has been made to use DSP techniques, the next decision must be where to place the ADC in the signal path.
traditional computer analysis of data is its speed and efficiency
in performing sophisticated digital processing functions such as
filtering, FFT analysis, and data compression in real time.
