Dsp Chip Connects To Adc Over Serial Port - Each fan turns off when the
temperature drops 5 degrees below its turn-on temperature. For example, if the dial is
set to 80 degrees, the fan turns on at 80 degrees and turns off at 75 degrees. This
prevents the fan from cycling on and off rapidly, which would occur if the fan turned
on at 80, started to cool the cabinet, and then immediately turned off at 79.

Envelope Follower Combines Fast Response Low Ripple - (07/(07/94 EDN-Design Ideas
/ (added 3/03) Fig 1's envelope tracking circuit solves the problem of receiving
ac-coupled NRZ data over a coaxial data link. Because the spectral content of the NRZ
data approaches dc (even with alternate frame inversion), the signal tends to
integrate in any ac-coupled stage preceding the zero-crossing detector, despite the
low cutoff frequencies. Thus, the dc level of the received data wanders, changing the
relative switching point at the comparator..... |
