Abstract
A ones bit density monitor is disclosed which is comprised of a 31-bit shift register, a counter, and a clock circuit having logic to preclude the number representing a number of pulses within the shift register from changing whenever a pulse is simultaneously input and output from the 31-bit shift register. To accomplish this, the counter increments every time a pulse is input to the 31-bit shift register and is decremented every time a pulse is output from the 31-bit shift register. Once the count reaches the number four, the ones density monitor circuit, and more specifically the counter, outputs a signal reflecting that a carrier is back on line.
