    I am presently working on to count out the no of pulses within some time period,so i have used CD4026BE IC as the BCD counter as well as display driving purpose which have to produce a,b,c,d,e,f,g as its output according to the no of pulses it has already counted out ,but there is some problem that has occured in my experiment, I have got a,b,c,d,e,f,g fluctuating simultaneously.
    It should produce b,c for 1, a,b,g,e,d for 2 ,etc, etc.
    I can't undertand the problem in my work.
    Pulses are in square waveform.
    Pls provide some suggestions as soon as possible...
