COUNTERS

Counters form an indispensable component of digital equipments. Counters quantify the frequency, and the inverse time period. They are used as frequency dividers where the frequency of a given pulse waveform is divided. Counters are sequential circuits that count the number of pulses given to the input terminal. Their clock pulses can be either in binary code or BCD form. The main properties of a counter are timing, sequencing, and counting.

Counters work in two modes.

  1. UP counter = EE reads in ascending order from 0 to 1
  2. DOWN counter = EE reads in descending order from 1 to 0

Counters can also be classified as ripple and synchronous counters. MOD-16 is a binary counter, while a MOD-10 is not. Both can be operated either by synchronous ...
