... ‘ Using vectorization = %.3f\n ’ , tstop − tstart); 2.14 USING MATLAB FOR PROCESSING SIGNALS We are now in a position to use MATLAB to process some signals. Once a signal is sampled (in digital ... binary 1s to 0s and vice - versa), and moving the position of bits within an integer. Bitwise operators are used in signal processing for encoding binary information for communications and storage. ... CHAPTER 2 MATLAB FOR SIGNAL PROCESSING It is worth noting that DSP systems are often developed in MATLAB, and implemented on the target hardware using the C language. This is because MATLAB provides...
