Hello there, I am a high school student in an engineering course, currently learning about audio and video processing, and my group was interested in demonstrating the quality difference between 2 very different quality computer microphones, and seeing what could be done to improve one of the microphones to about the same quality as the other one. Our teacher told us that to accomplish this task, we would need to obtain a VI of a high pass and low pass filter, and we seem to be having a bit of trouble locating them. Can anyone help us out? Thanks so much!
