| Abstract: | In this article we introduce briefly noise and interference and analyse the basic principles of shield in detail. Furthermore, we suggest a shielding design method ,which has proved effective by testing. This would ensure reliability in use and precision in measurement of low frequency and low noise amplifier. |
