Thus, the entire power consumption is reduced, and since the frequency is divided by the synchronous counter 5 at the post-stage, the delay in the frequency division output is almost constant at the post-stage and the no sequential delay toward the number of stages is caused. Thus, even ...
There are several classes of frequency counters. Basic frequency counters provide measurement of frequency only. Universal counter-timers are two-channel instruments that provide measurement of frequency, period, phase, totalize (the total number of pulses generated by some type of event over the durat...
A method of programming binary ripple counters for adding or subtracting counts to provide any integral division ratio is presented. The technique is particularly useful in extending the range of a given counter chain a few counts beyond the normal binary count. Thus, a 4 bit binary counter ...

Applications requiring the division of a signal of predetermined frequency by various divisors are quite common. The general class of frequency divider circuits typically receives, as an input signal, a reference clock signal with a fixed frequency. Previous frequency divider circuits have divided the ...
Remember that the prescaler and counters have to be chosen such that their maximum input frequency specifications are adhered to. (3) Check result using Eq. (5.1). A + PM = 3 + 57 × 16 = 915. (4) Consecutive channels are obtained by incrementing A. Maximum A for given M and P ...
First is that the calculation of the input frequency is a division, it will almost always have a remainder, that you do not see as it is an integer division. Second is that the quartz crystal oscillator isn't temperature stabilized.
