Filter Before Or After Amplification at Raymond Curry blog

Filter Before Or After Amplification. If you're trying to use a sophisticated filter,. A question that comes up often is “should i place a lna before or after the filter?” while it’s easy to experiment with both configurations, it’s worthwhile to understand why. Therefore it is best to filter the signal before (or while). If you're just using a simple rc filter, then you might as well put it before the amplifier. As @jazzmaniac said, an implemetation might yield slight difference, for instance at both ends of the signal, especially with iir filters (or iir derivatives). When filtering you attenuate the signal, and when you amplify, you amplify both the signal and the. When filtering you attenuate the signal, and when you amplify, you amplify both the signal and the. A filter attenuates out of band frequencies that could overload the gain stage if it was inserted before the filter. If you have a filter in front of the amplifier then it is necessary to ensure that the filter itself does not introduce significant noise.
