Automatic testing method of filter

Abstract

This invention dislcoses a filter automatic test method, includs following steps First step: Starts and inputs the filter correlation parameter and the function; Second step: Transfers and carries out the impulse signal to measure the test example; Third step: Transfers and carries out the white gaussian noise signal to measure the test example; Fourth step: Transfers and carries out the enormous minimum to measure the test example, in execution above second, third, and in fourth step of process, if the impulse signal measured the test example, the white gaussian noise signal measured the test the enormous minimum measured immediately the test example three center any result analysis is not correct, will stop the entire flow the execution, and will produce the impulse signal to measure the test example, the white gaussian noise signal measured the test the enormous minimum measured immediately the test example will correspond wrong prompt.

Description

technical field [0001] The invention relates to testing technology in the field of electronics or communication, in particular to an automatic testing method for a filter. Background technique [0002] In the field of electronics or communication, many devices or systems need to apply filters, especially in the radio frequency and intermediate frequency processing part of wireless communication equipment, digital filters are widely used to realize the conversion of radio frequency signals to baseband signals. According to the design requirements of the system, the technical difficulty and cost of actual implementation, the digital filter is mainly realized by ASIC / FPGA chip (ASIC: Application Specific Integrated Circuit FPGA: Field Programmable Gate Array) to realize the filtering The ASIC / FPGA of the digital signal processing algorithm of the device is called algorithmic logic, which generally has the characteristics of large calculation scale, complex structure and difficu...
