Title The amplification of High-frequency signal Which has a Small range
Abstract
For high frequency signal generator, a low level signal, the need to enlarge discrete components, so that the receiver can receive the signal. In order to build a reasonable and practical application of the amplifier circuit can, go to the access to information and books, learn how to solve problems similar to the past and ideas. Then, I need to fully understand the working principle of discrete components and design a viable option. And calculate the quiescent operating point to ensure its zoom magnification within a stable range of the signal.Then calculate and simulate successfully completed build out circuit according to the schematic in the laboratory observation, statistics and test and document the status of the circuit board and the problems encountered. After analyzing the causes of the problem of feedback problems, and then propose a solution, and in this experiment, whether the distortion and noise waveform display via an oscilloscope to determine whether compliance with the requirements of the experimental results.Finally, lessons learned and experience throughout the experiment, and if there is need to carry out more in-depth analysis and reflection.
