Hey i am looking to build a quadrature encoder and i was wondering if i could use a microcontroller to create the outputs or do i need a separate input?
Also if you can what would be the best microcontroller to use?

Microchip posted a Technical Bulletin for using a PIC10F2xx uC as a quadrature encoder simulator.

Source code is available here: http://projects.mestcs.com/idcplg-IdcService=SS_GET_PAGE&nodeId=2121&fragment6_NextRow=326.htm

Here's a quadrature decoder using flipflops and a few gates: http://www.fpga4fun.com/QuadratureDecoder.html

Here's a simple quadrature encoder circuit using phototransistors and Schmitt triggers:

You could use a 4093 quad NAND Schmitt trigger for that portion of the circuit.

You could probably build a quadrature encoder simulator using some D-type flip flops with a clock input.

A separate input for each output is always a requirement, but only in professional plumbing applications.

:D

(try posting again, as your post needs more sense: your post makes none.)
