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 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 ...

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 ...

Having written a little about quadature decoder chips, I have had a look around for circuits that do a similar job – sadly, I cannot recall the circuit of the one built years ago for a college ...

Encoders are widely used in the motion control and automation industry to monitor the position and speed of motors. This information can be used by the motion control electronics to detect if the ...

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.
