Canton, Mass. — United Electronic Industries (UEI) released the DNA-QUAD-604, a four-channel quadrature encoder input board designed for use with the PowerDNA, UEILogger and UEIPAC data acquisition ...

Suiting use with the vendor’s PowerDNA, UEILogger, and UEIPCA data-acquisition and -control cubes, the four-channel DAN- Quad-604 quadrature-encoder input board provides standard A, B, and Z index ...

LSI Computer Systems (LSI/CSI) has created a family of 63 tap (6bit) digital potentiometers for direct connection to quadrature decoders, push buttons, GPIOs or SPI serial controls. Debounce circuits ...

Quadrature encoders have many uses in position-sensing applications. This implementation uses a Xilinx complex programmable logic device (CPLD) to count the pulses from the encoder and determine the ...

Encoders are widely used to help control machine position and speed. Typical encoder output, a series of quadrature signals, consists of two full square waves, offset by 90° in phase. The number of ...

This article is part of the Ideas for Design Series: Vol. 3, No. 8. In many applications, accurately sensing the position of an electrically controlled mechanical device such as a motor is critical.
