In situations where it is desired to provide a serial output from a computer operating in a liquid helium environment (4.2 degrees K) to a receiver operating at room temperature, where signal repetition rates are of the order of 20 megabits per second, the receiver required would have rather large gain-bandwidth requirements and consequently would be relatively expensive. A narrow band receiver can be utilized if the data being transmitted is held in DC powered latches for approximately 10 machine cycles.
