Applications using the ADE7756** - AN-578
Analog Devices Application Notes. The
document describes implementation of an rms
signal processing algorithm using ADE7756
and a Microcontroller (PIC16C63) from
Microchip.

Celsius to digital thermometer works with
remote sensor - EDN-Design Ideas / You
can use a single-supply system to precisely
measure temperature at a remote location
with less than 1°C error over a 0 to 100°C
range (Figure 1). The circuit includes T1, a
low-cost AD590 temperature sensor; IC1, an
AD8541 rail-to-rail amplifier; four
resistors; a trimming potentiometer;
**Class A JFET Opamp Circuit** - First
Generation design... that means it is not
our latest design.

Model Fixed Point DSP Arithmetic in C -
EDN-Design Ideas You can run initial
high-level simulations of custom numerical
algorithms, such as digital filters, using
floating-point numbers in an environment
such as C or Matlab. Unfortunately, you
won't see include fixed-point effects, such
as truncation due to limited precision and
register overflow, until you use a Hardware
Design Language (HDL)

RISC µP Implements Fast FIR Filter - EDN-Design
Ideas When it comes to implementing a fast
FIR filter, current RISC µPs can compete
with DSP µPs. The FIR algorithm continuously
implements the following equation: N=n–1
Out=Sum[in(t[-]n)coeff(n)] N=0
**Single Amplifier 4 Band Passive EQ**
Subwoofer Equaliser - The Linkwitz
transform circuit is a hugely flexible way
to equalize the bottom end of a sealed
loudspeaker enclosure. A speaker that is
corrected using this method is flat from
below resonance to the upper limit of the
selected driver. The low frequency roll off
point is determined by the parameters of the
transform circuit

Video Emitter uses Battery Power - EDN-Design
Ideas The block diagram in Figure 1 shows how to make
a cable-free, direct-video system. The system allows users
to walk from booth to booth at an exhibition to interview
people and to display the interviews in real time on three
screens at key locations. You can use the small and simple
system each. |
