Hi kalpak,

infact i myself suggested prahlad to do so personaly. this was on the fact taht the digital filter inside the chi is a chain of delay elements (D-type flipflops) clocked by this Tclk. they shift in the samples @Tclk. and then a AND block tests last three inputs samples. if any one is diffrent input is discarded. My point was exactly what Kalpak says. If frequency is very high then even these high freq undesired pulses will also be taken as inputs.

prahlad conducted tests and concluded then that reducing the frequency worsts the conditions even. So problem is somewhere else.
