    Automatic Pipe bending machine

    Hi Jagan, Each motor has a way how to drive it. Specially if you want to control its speed or torque. So, we need more information: What motor you need to drive? (Type, torque, size, etc) What control you need? (speed, torque, etc)

    HC08 Problem as some outputs are turned on

    I am designing a new system with the MC908GR32A microcontroller and some outputs (active-high) are unexpectedly turned on. I am thinking that its a reset problem. Somebody ever had a similar problem? Thanks, Milton

    Help in Darlington Array ULN2003A

    darlington array No. Inside of the chip you have some resistors that makes the polarization. But, for safety, you can use a resistor for power dissipation. Thus, you put a resistor serially with the ULN2003A emitter (output). look at ULN2003A datasheet for more information. ok? []'s

    FFT FILTER DESIN BY USING VHDL/VERILOG

    fft filter vhdl hi, you can make a iir filter in many differently ways. look at an specific book... like "Digital Signal Processing" by Alan V. Oppenheim and Ronald W. Schafer or look at MATLAB (release 14 at least) tutorial. There are many ways to do a iir filter in a digital computer...

    question about de-emphasis filter for digital audio

    de-emphasis filter Hi, Emphasis filter are used to give emphasis in the higher frequency components on filtering process. This filters (Pre-emphasis and De-emphasis) are used in systems in which the power spectral density of the signal decreases more rapidly than the noise power spectral...
