The count sequence of a BCD down counter is as follows: 1001,1000,0111,0110,0101,0100,0011,0010,0001,0000,1001. . . . . . .
8 flip flops. a counter composed of n- flip flop and any counter will count from 0 to 2^n - 1. i.e 2^8 - 1=256 - 1 = 255
A digital counter than can count both up and down, selected by a control signal.
a digital countdown timer is simply a digital synchronous counter consisting of registers and flip flops example :to count the number from 0 to 15 we require a four bit synchronous counter which will pass to sixteen stages continuously with shifting from one stage to other after every clock pulse and the cycle continues

Three decade counter are required to count 999
It takes nine flip flops to count from 0 to 511.

1 is the highest number you can count to using a mod-2 counter.
mod 8 counter mod 8 counter

i think its better to count and count and count and think of yourself,your loved ones...thats what matters most...
Probably the same. A frequency counter is specifically intended to count frequencies, but an electronic counter could be counting anything.
An up counter is simply a digital counter which counts up at some predefined increment. A Binary Up Counter with 'n' stages can count up to 2n states.If we are implementing Up Counter with flip flops, this 'n' stages becomes the number of flip flops. For example a 4 bit Up Counter can count from binary 0000 to 1111, i.e 24=16 states.A detailed design and working animation of of Binary Up Counter is given in the related link section below
