DAC and µP Implement Hardware Window Generator - 03/31/94 EDN Design Idea A typical DSP system first converts an analog signal to digital,
then performs windowing, and finally does a fast-Fourier transform. However, you can accelerate this process by
swapping the converting and windowing steps and impl. . . [by Sergey Velichko, Extended Systems, Boise, ID]
DAC and flip-flops form constant-current-source - 04/23/09
EDN Design Idea Using two flip flops, you can program a serial-input DAC to produce a constant 4 mA. . . [by

DAC and op Amp provide variable-control voltage - 12/06/01 EDN Design Idea Early DACs contained standard R-2R ladder networks, and produced
a negative output voltage. These early DACs, such as the MAX7837/7847 and the MAX523, require both positive and
negative supply rails to accommodate their negative out. . . [by Chad Olson, Maxim Integrated Products,
Sunnyvale, CA]
