hey how come i suddely got
a red light
in my rep ratings???
anyways... as i was surfing through i came across some sites where it was mentioned that
the easiest way to convert
a square wave into
a sine wave is to add
a low pass filter.. agreed, as it will just keep
the fundamental freq and discard all
the odd harmonics.
in addition to it they had mentioned some filters - bessel, butterworth and elliptical - each one with some specified octave..
following is
the link to one of
the pages.. and i have attached one schematic too for easy reference...
**broken link removed**
i am planning to remove
the frequecy divider ic and am thinking of giving
the crystal oscillator output directly to
the filter ic.
what i want to ask is which filter will serve my purpose
in the best possible manner and with what configuration if any.. ( have never dealt with filters before ) and also,
the particular filter ic given
in this schematic is not available
in the region i live.. can anyone pls suggest me any other ics with similar functions?
thanks..
( this forum
has been of great help to me.. god bless
the makers of this forum.. hope this helps
in removing
the red light..
