It means cycle of data transmission between the master station and the local station. It does not mean the time required for an input signal to be output. How to Calculate the Simple Transmission Time Transmission Rate 0 bps Simple Transmission Time (sec.) = (No. of data bytes from master station + No. of data bytes from local station) 0. + 0. Transmission Rate 00 bps Simple Transmission Time (sec.) = (No. of data bytes from master station + No. of data bytes from local station) 0.0 + 0. Effective Transmission Time The effective transmission time means the time required for a change of an input signal to affect its output signal. It varies between the minimum and maximum values, depending upon the timing of input change. Minimum Time = Simple Transmission Time Maximum Time = Simple Transmission Time DAST-0 SPECIFICATIONS ES- Rev. Page /
