Input and Output with the DSK • • Input and output with the onboard AD535 codec (alternative input and output with the stereo codec PCM3003 are described in Appendix F) Programming examples using C code 2.1 INTRODUCTION Typical applications using DSP techniques require at least the basic system shown in Figure 2.1, consisting of analog input and output. Along the input path is an antialiasing filter for eliminating frequencies above the Nyquist frequency, defined as one-half the sampling frequency Fs. Otherwise, aliasing occurs, in which case a signal with a frequency higher than one-half Fs is disguised as a signal with a lower frequency....
