Digital signal controls sine generator - 15-May-03 Issue of EDN The
circuit of Figure 1 produces an accurate, variable-frequency sine wave for use as a
general-purpose reference signal. It includes an eighth-order elliptic,
switched-capacitor lowpass filter, IC3, which uses a 100-kHz square-wave clock signal
that microcontroller IC2 generates. (Any other convenient square-wave source is also
acceptable....[Design Idea by Simon Bramble, Maxim Integrated Products, UK] |

DIY remote control based on PIC - Control up to 8 devices by this easy
constructable remote control. It can work as a radio or infrared remote control,
depending on the components. Each device output can be configured to be momentary
(turned on while you press the button) or latched. Latched outputs can be toggled
on/off by one button per channel, or turned on and off by two buttons per
channel….(electronic circuit added 7/03) [Peter Jakab, Electrical Engineer, Engineer

Double your DSP cores for GSM base-station processors. - 04/01/99 Issue of
EDN Lucent Technologies’ DSP16410 provides 800 million multiply/accumulate (MAC]
operations per sec, letting designers of baseband processors for Global Systems for
Mobile communications (GSM] and other cellular-standard base stations pack more
channel processing into an equivalent pc-board area with low power consumption. The
latest in Lucent’s 16-bit, fixed-point DSP 16000 series, the 16410 has two DSP 16000
cores, each....Page includes several designs. Scroll to find this one....(EDN

Dremel Speed - The circuit at right uses a logi-level N-channel FET driven
directly by the PIC. The PIC creates a variable PWM signal to power the
motor. Motor current is sensed using a combined 0.5 ohm resitance to ground.
