PPT-Sampling and Reconstruction of Signal

xt xt Sound is audible in 20 Hz to 20 kHz range f max 20 kHz and the Nyquist rate 2 f max 40 kHz What is the extra 10 of the bandwidth used Rolloff from passband to stopband in the magnitude response of the antialiasing filter. Decimation or downsampling reduces the sampling rate whereas expansion or upsampling fol lowed by interpolation increases the sampling rate Some applications of multirate signal processing are Upsampling ie increasing the sampling frequency before D Husheng Li.
