Title:
VELOCITY MODULATOR
Document Type and Number:
Japanese Patent JP3851132
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a velocity modulator which can sufficiently obtain a velocity modulation effect even when a video frequency is widened in band.
SOLUTION: A first velocity modulation pulse signal Pa1 and a second velocity modulation pulse signal Pa2 are individually synchronously applied from a fist amplifier 13 and a second amplifier 1 to a first velocity modulation coil 14 and a second velocity modulation coil 15. Thus, a transistor having high-frequency characteristics which cannot have been heretofore used, can be adopted, and hence the sharpness of the image quality of the vido signal can be improved in wider bandwidth.
