In the figure is the frequency divider (CD4040) of converting the 50Hz or 60Hz into their 1/60. As CMOS is integrated, and it's multi-stage, so a CMOS integrated circuit can divede the 50Hz or 60Hz signals, and they are output at the period of 1min. This circuit is installed with a 12-stage counter CD4040AE, which can switch the 50Hz input pulse signal into the output pulse whose period is 1min, the dividing coefficient is 50×60=3000. The way to change the decimal 3000 into to binary is to divide 3000 by 2 continuously, all the even number is marked as 0 .
