Richards, Mark A. · Defense Technical Information Center (DTIC) · 2004
Digital Signal Processing is "...That discipline which has allowed us to replace a circuit previously composed of a capacitor and a resistor with two anti-aliasing filters, an A-to-D and a D-to-A converter, and a general purpose computer (or array processor) so long as the signal we are interested in does not vary too quickly." - Prof. Tom Barnwell, Georgia Tech
