<p>The sprocket signal processor is adapted for record member readers wherein the record member is subject to oscillations or jitter due to its advancement over a sensor. To prevent the recognition of erroneous signals and in particular sprocket hole signals reduced on the record member with the data for controlling the read out of the data, the sprocket signal is processed so as to block out erroneous signals and to provide only the desired sprocket hole signal for read out purposes, thereby preventing erroneous read out of the record member.</p> |
