| Abstract: | With the generation principle, statistic characteristic and non-leakage of pseudo random signal proven, a technique of pseudo random exciting by means of tape recorder for modal test is pre(?)ented comprehensively. Several application examplea demon(?)trate that the method is a good modal test technique for common manufactories and laboratories, ease for signal generation, satisfaction of signal qualities, convenience to control spectrum, and simplicity of test equipments. |
