T-codes are variable-length codes that have been shown to provide excellent codeword synchronisation properties without any sacrifice in coding efficiency. Previously published results have used simulation techniques to ascertain the synchronising properties of each T-code. The author presents the first theoretical technique for calculating the synchronising delay of a T-code based on the code set's construction. The development of a database of best T-codes from which an optimally efficient code with superb synchronising properties can be easily chosen is also documented.
