Calculating the required number of bits in the function of confidence level and error probability estimation

This paper proposes the calculation of the required number of bits transmitted in the system, in order to achieve the desired level of confidence. Proposed solution is based on the selected value for the bit error probability, and statistical confidence levels. In addition, required error probability for telecommunications protocols and data transfer protocols is discussed, overview of the BER (Bit Error Ratio) testing equipment performance is provided, and compromise of testing time in relation to the statistical level of confidence depending on BER is examined.
