Title: THD, SNR, & Noise Measurement of filter Post by RC on Apr 13th, 2003, 10:18pm I need to measure the THD, SNR, and Noise performance of a filter. It is a low-pass filter with 10MHz cut-off frequency. My doubts are: 1. how to measure the THD? using Signal Analyzer/Spectrum Analyzer. what input signal level, signal frequency I should use? upto what hormonics the THD should be taken into account? 2. how to measure noise? short the input to ground? or noise source needed? may I use 50Ohm resistor? 3. SNR? may I take the output foundamental to noise floor??? Thanks. |
