摘要:
The time at which a signal is received at a receiving station is recorded in code form on unmarked recording medium by encoding the time registered on a clock mechanism. A pulse code device driven by the recorder drive mechanism is rendered operative to record groups of signal pulse trains separated by spacing signals. Encoding devices select the number of signal pulses in each group in accordance with the time registering positions of timing wheels associated with the clock mechanism.
