Transmission of analog signals through acousto-optical devices

Acousto-optical devices are capable of processing digital and analog signal s. A theory of transmitting information through acousto-optical devices dev eloped earlier is extended to the transmission of analog signals. A resolut ion criterion based on the requirement of transmitting a required number of signal gradations with a specified reliability is studied. It is shown tha t the acousto-optical equation in which the number of resolvable points is defined as the time-bandwidth product must be modified for the case of tran smitting signal gradations.
