12 flip-flops in series can divide by 4096. 20.48 MHz divided by 4096 is 5 KHz.
Other division factors are possible, but 4096 is the maximum.
The word ripple in ripple counter refers to the fact that the carry ripples from one flipflop to the next, instead of being pre-calculated by logic so that all the flipflops in the counter change state synchronously. Thus the bits in a ripple counter change state asynchronously with the most significant bits changing last. This can produce race conditions and instabilities in logic circuits that are driven by these counters.
A ripple counter is a counter in which state transitions of one or more flip flops are triggered by the outputs of other flip flops in the circuit. If all flip flops in the counter are triggered by a common clock pulse, then the counter is called a "synchronous counter". a ripple counter is a counter that will ripple through the information sequentialy. .
You do it by studying, and doing your homework by yourself instead of trying to get someone else to do it for you.

Probably the same. A frequency counter is specifically intended to count frequencies, but an electronic counter could be counting anything.
A heart beat counter circuit typically consists of a heart rate sensor connected to a microcontroller (such as Arduino) which processes the sensor data and displays the heart rate on a digital display (such as an LCD screen). The heart rate sensor measures the electrical activity of the heart and converts it into a signal that the microcontroller can interpret. The microcontroller then calculates the heart rate based on the sensor data and displays it on the screen.
Frequency counter
A frequency counter is a type of electrical component frequently used by technicians. Its main purpose is to measure high frequencies.
One would measure hertz by using an analog ammeter. Hertz can be measure in kilohertz. Hertz is the unit used to measure frequency. Any instrument that measures frequency can be used to measure hertz. 1 hertz is 1 cycle per second. By radio frequency.
designed a sequential circuit that will function as 2 bit-up down counter
I'd probably just use a higher frequency source and a counter. Count the number of 555 toggles per period and you have the frequency.
Yes. The instrument is referred to as a "frequency counter". It's a common piece of telecommunications test equipment.
