Parity Check Problem

You have saved my exams!

excuse me sir,where is the next video

So What's the way of solving this problem if there is a 33% chance that the receiver will not be able to catch the error?

Very helpful Thankyou so much

I want to know what grade hes teaching. Im in 9th we are learning this now

wow what a way to teach! Thank you so much!!!

Got my gcse tommorow and had the same crap teacher for two years, bless your teaching style 🙏🏻

I learned more in 3 minutes than my whole year of Information Process Technology course lol

thank you alot .

your videos helped me alot to study for my exam.

Please replace yourself with my teacher

What a fantastic teacher! I wish more teachers were as passionate and understandable as you. Please keep the videos coming.

thank you for this! - suffering student in singapore

So helpful and enjoyable at the same time. Thank you!

Dear +Eddie Woo, this is awesome! Great explanation.

However, I'm not sure about your probability calculations. Shouldn't one include the chance of interference?

Suppose the chance of a bit getting flipped is 1% (I don't know if this is accurate).

Then the probabilities should look something like this:

1) Both bits uncorrupted: (1 - 0.01)^2 = 0.9801
2) One of the bits corrupted: (1 - 0.01) * 0.01 * 2 = 0,0198
3) Both bits corrupted: 0,0001

The parity checking should respond correctly to 1 and 2, and therefore 99,99% of all errors (given interference prob of %1).
Which is much larger. Even if the chance of corruption is 10%, still the parity checking should respond correctly to 99% by the same logic.

This might be nitpicking, but please do tell me what you think about the observations above.

Thanks again for so many great videos.

Best teacher I have ever learnt from.

please helpe me

we neeeeed more teachers like you, it's so much fun this way, i don't really know how to find the words to tell you how awesome this is, but thank you so much :)))

Eddie who? Eddie Woo!!!

I wish I had you as a professor....mine is old, grumpy and makes everyone not want to ask questions because he responds as if we are stupid. He is also sexist.

I like your teaching style man! good confidence and fluency i really enjoyed it! i needed to know what this topic was for an exam soon and it really helped!

Thank you and continue to do well!

Hey Eddie Woo you would love One Note. Its free and it has the ability for inking and sharing notebooks with students in either editable or read only!

you are great , thank you

I like the way you teach. Already subscribed

hi i am from the middle east....
exactly from saudi arabia... i liked your videos.. as the others say.. i say that your way of teaching is great and motivaited... thanx alot..... i already subscribed in your channel.

Awesome way of teaching!

you are the most awesome teacher I've ever seen.... hats off to you....

How does even number of ones implies even number of zeros? I didn't get that part. Thanks!

You should offer an online course.  I would definitely attend.
Thanks

Love your way of teaching. You are one of an excellent teacher. Go ahead and I am coming here just to understand parity check.

Hi Eddie,

love your channel... Helped me a lot while preparing for information technology exam.
Thanks you very much!!!  I will recommend it ..  

Came across Parity Check while reading through the CompTIA study guide, I did not understand fully. Being able to visually see the process cleared it up in a minute and on top of it this was explained very well, thank you so much. 

Thanks Eddie. Brilliantly explained.

i want to ask, this single bit parity right?   how about for two-dimensional bit parity? can u show it how to detect error

Wow. You explained in 3 minutes & I understood everything while my prof. needed at least 20 min with an average understanding rate of 33% :^)
You are awesome! I'm gonna check out your other videos as well

so how do you use a parity check with both problems / prevent wrong message from being recieved ?

Hi Woo,

Just a question. This suff that your explaining like (Parity and checksum) is that in Univeristy class? Or are you just going around different schools. In other words, are you teaching in univeristy or high scholl? Because i am studying the same topic. I find your video really beneficial. Thanks

Sorry for my lanuage 

I need this for my quiz tomorrow lol. Thanks

I wish my teachers were like you man. Then I would actually look forward to class.
