the solutions here already, so this isn't helping me bypass doing homework or anything like that.) My professor has done an unsatisfactory job explaining this particular circuit's step-by-step functioning and so I'm really confused: how the columns are being generated and how the errors are detected. If anyone could help explain how this is working, I would appreciate it very much. Problem: For the single error correcting code circuit, fill in the response to reception as far as necessary, and determine if any error is detected and, if so, what symbol is corrected. Solution: the second from last position is corrected, yielding 0110100, time from left to right. UPDATE: I think I finally have a hard-fought understanding of this circuit, except for one issue. If you could take a look at this proposed explanation and see if it's correct, I would again be very appreciative. This is an error-detection circuit. It will tell you where the error in the given codeword is by outputting a

At least two logic gates receive inputs from a plurality of circuit elements. The plurality of circuit elements crc error detection are coupled to receive and store a portion of a bit stream. At the end of a CRC error detection division operation, each circuit element corresponds to a bit in a bit error pattern syndrome and the logic gates determine if the contents of the circuit elements match specific bit error patterns. The circuit causes the state of at least one bit in the bit stream to change if the contents of the plurality of circuit elements match one of the specific bit patterns. The circuit is advantageous in that it may detect single bit errors, and double bit errors that may be caused by error duplication characteristic of a scrambler. Images(6)Claims(10) 1. A circuit for detecting and correcting errors in a bit stream, said circuit comprising: a. a plurality of bit circuit elements coupled to receive and store said bit stream, each bit circuit element corresponding to a specific bit in a bit pattern; b. at least one operation circuit element for performing operations between contents of at least two of said bit circuit elements; and c. at least two logic gates fo
