I wrote a bit of VHDL for generating inc/dec pulses from quadrature rotary encoders like the CTS Electrocomponents ones I bought from Digikey for a project I worked on recently. This debounce circuit ...

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 ...

Quadrature encoders work inmany applications to determinedisplacement and direction of mechanicaltravel. They vary in design, butthey all do the same thing: supply a setof square waves 90° out 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.

Quantum Devices’ QM22 series of optical incremental encoders measure 22 mm in diameter, allowing for integration into tight spaces. These are modular encoders are designed for high volume OEM ...
