Abstract :
THE broad objectives and application principles for the P1 carrier system opened a new field of use for carrier equipment. However, to exploit this field, several new requirements had to be met. These demanded that the system be of substantially lower cost than any before, that it use only a small fraction of the power, yet maintain the quality associated with a carrier system.
