## State Transition Diagrams for Counters

I am wondering how to draw a state transition diagram for a two bit counter with the same reset capabilities of a register. I am also wondering if this reset signal is asynchronous what does this change about the output function and is it a Mealy Machine?

## [moved] Time-code decoder - SMPTE - BiPhase Mark - clock recovery - full design

This implies that by counting constant consecutive samples we can determine if a constant value is LONG (6 samples) or SHORT (3 samples). This can be done using a shift register of 1 bit (FF). For initialization purposes, we have to wait for the first transition. Then we increase a counter until the value changes. Compare the

## Why gray counters work?

Hello, When designing an asynchronous FIFO - Gray counters are used for the pointers. This is because - Gray has the benefit of not more than a single bit is changed between adjacent count values. But what if the frequency ratio between clock domains is so big that more than one value is incremented during one period of the slow clock domain

## Synchronous Counter Using D- Flip Flop(Verilog)

You're lucky I wasn't the first one to reply to this post...I would have given you the following code: Well, he got me at prime numbers. And then lost me again when showing a picture that has nothing to do at all with prime numbers. Just a regular boring down counter with no relation whatsoever to prime num

## how to eliminate initial state of counter

Hi everyone this is a counter i made F,b,a,9,8,7,6,5,4,3,2,1,0,F,b... i intend to make a counter which i s b,a,9,8,7,6,5,4,3,2,1,0,b,a,9,8,7,6,5,4,3,2,1,0,b i need to remove the F, how do i do this. here is the circuit..can someone help me to fix this...thank attaching the multisim file for editing.

## how to separate a string of data into even and odd data?

Welcome to the real world.(of concurrency) what is the condition on which you want separate the two data streams? e.g. if you want to separate them on each clock edge... you can have a bit counter (a T flop) and use its output as select line to a 2:1 multiplexer. At every odd transition you can separate the data. else just connect your sign

## Counter which counts every transition of a clock pulse

Is there any counter which counts the every transition of a clock pulse? For example when the pulse is high, the counter counts one, and when it goes low, it increments it by one again. This means that for one complete cycle, counter counts two. Is it possible? If such type of counter is not available then (...)

## Can I make interrupts with other ports than Port3 in 8051?

2) Not on the vanilla 8051, but on 8052 and its derivatives the Timer2 input on P1.0 - set Timer2 as counter and preset it so that a single transition would roll it over and trigger an interrupt. OK this is a trick and no other pin can be used like this, but your question was "any other than P3" and this is "any other" isn't it... :-D wek

## how to generate only one rectangular wave???

emmm... i m also confuse with my question ;-) sorry about my lame english, but it is 1 shot button switch and i want to use it to change my counter state, usually we use clock with periodic rectangular waveform right? but this time i want to use only "one rectangular wave" so that i can see my counter change it state when i m pressing the

## how to detect start bit in uart

The best way is detect the fall transition with a fall detector, start to count whit a clock 16x respect your baud rate and when your counter is 8 then sample the state of the line, if you detect zero then you have a real start bit otherwise your fall edge was a spike. if you detect a start bit you can sample the data every 16 times with the clock

## Measure the time period between 2 signals

Hi, Your design seems to work ... But after the first display of the counter value, the only way to restart the count is to set sw to 0. If not, your state machine "decide" will stay at 11 state. To help you in debugging, draw your state machine and check that you did not forget any transition between states, and that all states are defined.
