Résumé du livre
A program was carried out to verify the feasibility of the PACM-FM Telemetry System concept. The tasks carried out were (1) design and construction of a PACM-FM ground station, (2) design and construction of a vehicleborne data converter to generate PAM, PCM, and PACM formats, (3) laboratory test with various formats and data rates to establish system performance, and the capabilities of the equipment developed, (4) analysis and evaluation of the PACM-FM system to predict equipment electrical and operational characteristics, (5) preparation of recommended procurement specifications based on tests, analysis, and evaluation. The tests and analysis disclose that the performance obtainable for PAM and PCM in the PACM format is the same as in the pure PAM and PCM formats. The performance attained agrees with that which had been predicted earlier. It has been found practical to handle all data in the ground station on a unified basis for storage; display, and processing regardless of the form in which it was transmitted. The system has been found to be feasible in every respect. (Author).
