Stability of Tandem Regulators in the L-1 Carrier System

The L-1 coaxial carrier system, with its dynamically-regulated amplifiers, has envelope gain in the vicinity of two cycles per second. With a large number of such amplifiers in tandem, the transient response to an input step function has a peak-to-peak amplitude, or oscillation, many times greater than the size of the initial step. It therefore is necessary to insure that the over-all envelope gain is not so great that small input disturbances normally occurring in system operation are magnified to a point where transmission is impaired. Calculated effects agree with experimental observations with small steps.
