Method and apparatus for testing magnetic bubble devices by varying the components of input signals |
摘要 |
Disclosed herein is a method of testing a magnetic bubble device which guarantees allowable variation ranges for a variety of signal components of input signals applied to a magnetic bubble element when the magnetic bubble device is to be energized. A variety of signal components are varied in a testing cycle for writing, reading and collating information, whereby a plurality of combinations of the variety of signal components are obtained. The obtained input signals are continuously applied to the bubble element to effect the test.
