The primary focus of this research paper is to study the automated test station to determine the cut-off frequency. The study was conducted for the low-pass filter in the frequency range 50 Hz – 100 kHz. A preliminary test was conducted using 10 filters whose cut-off frequencies were measured. The main blocks of the station are described, emphasizing some originality. The test results depict a high degree of accuracy as such were manually checked to confirm the effectiveness of the test station. The automated test station was also developed to include provisions that allow the results to be stored in a spread sheet file against each filter serial number. This is a unique feature of the measurement system.
