            Abstract : 
This paper reports on a theoretical treatment of the noise figure for iterative travelingwave parametric amplifiers and gives experimental data from noise figure measurements made on such an amplifier which operated at 1.7 kmc. Using information about the diodes supplied by the manufacturer (Microwave Associates) we calculated from the theory a double-channel noise figure of 1.3 db. The measured noise figure was 1.2 db,
