I am looking for a way to check if 2 permutations (represented by lists) are of the same parity. Note that I am not interested if they are even or odd parity, just the equality. I am new to Python and my naive solution is given below as a reply. I am looking forward to Python gurus showing me some cool tricks to achieve the same in less...
I want to convert a Character to a 7 bit even parity. Can you please suggest me, how to implement this? ...
I'm trying to get a simple serial reader going in C# to read info from an rs232. I'm using VS2008. I can receive data fine with hyperterminal and python but I keep getting parity errors every time I try to transmit a character to C#. Number's work fine, it's just the characters. It's configured exactly the same as hyperterminal: 9600baud...
Are there any known problems with using a serial port set for 8 data bits, 1 stop bit and even parity, under Windows XP? ...
Is there some instruction in MIPS that will determine the parity of a certain bit representation? I know to determine whether a "number" has an even parity or an odd parity is to XOR the individual bits of the binary representation together, but that seems computationally-intensive for a set of MIPS instructions... and I need to do this ...
Hi guys, I was reading about error detection and stumbled upon a statement which I didn't quite understand. The statement said "for a k bit string we need lg k parity bits to detect 2 bit errors".where lg is log to the base 2 I couldn't quite understand why this is true, is there any formal derivation that confirms this. The name of t...
Some student asked this on another site, but got no answers. I had a few stabs at it, but found it pretty tricky. Doing it with just the switches would require a 9:1 compression ratio, so I guess the trick is very much in the rules you assign to students. Perhaps every student needs a different set of rules? I've thought about allowin...
Hi Guys, I was reading about horizontal and vertical parity check codes. One of the properties of these codes is that the final parity check (the lower right bit) is equal to modulo 2 sum of horizontal parity checks and also equal to modulo 2 of sum of vertical parity checks. I did not understand, why this is true. I can see them in t...
