With Digital Signal Processing, you can manipulate signals after they have been converted from analog voltages and currents into digital form -- i.e., as numbers. Normal analog operations of filtering, mixing, and signal detection all have their parallels in the DSP world. Because the cost of complex digital processing is very low, DSP is often the preferred way to build high-performance communications systems.
