Digital Position Encoder Does Away withADC:  05/08/97 EDN-Design Ideas / (added 6/06)  

Encoder and PC Make Complete Motor Control System:  12/12/02 EDN Design Ideas  /  (added 1/05)  This Design Idea combines a simple ISA-bus-resident interface circuit; a garden-variety PC; a high-resolution optical shaft encoder; and a PWM-controlled, 0.05-hp, brushed, permanent-magnet dc motor to make a high-precision and high-power motion-control system. The system sequences the precise rotation of an evacuated steel bell jar several feet in diameter, such as those used in molecular-beam......

Hierarchical Priority Encoder:  Circuit design (added 01/05)

KEELOQ® Manchester Encoding Receive Routines:  Microchip Application Note Published 11-May-01   (app note added 2/06)

Optical Encoder Controls Range Switch:  10/08/98 EDN-Design Ideas / (added 6/02) Instead of using a counter-controlled, pushbutton-activated range switch, you can use an optical encoder. Inexpensive encoders are available, and they occupy minimal space on the front panel of an instrument. Moreover, an encoder gives you the opportunity to select the optimum operating speed. However, at positions near the transition points in counter position, mechanical shocks can provoke false switching. The circuit in Figure 1 overcomes the false-switching problem....  

PIC Based Packet Radio Encoder:  (circuit / schematic design added 6/06)

Remote Control Encoder/Decoder with PIC16c620 and PIC12c508:  (circuit / schematic design added 6/06)

Resolver to Digital Conversion; Simple Alternative to Optical Shaft Encoders:  AN-263 Analog:  Devices Application Notes  (app note added 6/06)

RF Transmitter uses AMI encoding:  11/24/99 EDN-Design Ideas / (added 6/06) Although alternate-mark-inversion (AMI) encoding is well-suited for direct-conversion FM transmission, designers often overlook the technique. AMI, a three-phase, synchronous-encoding technique, uses bipolar pulses to represent logic ones and no signal to...

Rotary Encoder Mates with Digital Potentiometer:  02/06/03 EDN Design Ideas  /  (added 1/05)  In developing electronic systems, designers look for products or ideas that may benefit from the better performance, smaller size, lower cost, and improved reliability that an IC can offer. Toward that end, the digital potentiometer emerged as an alternative to its mechanical counterpart, the mechanical potentiometer....
