31. Other formats are possible; 8 bits of data plus a parity bit can convey all 8-bit byte values. 32. Instead of writing two tones to tape to indicate bits, patterns of square waves are used including a parity bit . 33. The core memory had one parity bit on each digit for error checking, resulting in 60 bits per memory word. 34. The original SCSI-1 version of the parallel bus was 8 bits wide ( plus a ninth parity bit ). 35. All SDI-12 communications are transmitted in ASCII at 1200 baud with 7 data bits and an even parity bit . 36. IRA codes first repeats information bits different times, and then accumulates subsets of these repeated bits to generate parity bits . 37. Other formats have a similar structure of leading facility code followed by card number and including parity bits for error checking. 38. The parity bit is checked by the receiver to tell if an error has occurred in the transmission of the character. 39. With the addition of an overall parity bit , it can also detect ( but not correct ) double-bit errors. 40. The ICR consisted of 128 38-bits, with a half-word Parity Bit calculated and checked with each access.
