| #582 TinySA is 3KHz equal to 1KHz? In some measurements, the 3KHz bandwidth filter on the TinySA results in a spectrum similar to a 1KHz bandwidth filter on a typical spectrum analyzer . The width of the TinySA filters are fatter at the top compared to a normal gaussian filter but they are narrower at the bottom. Filters are specified at the -3dB width. The DSP type of filter on the TinySA also results in some out of band ripple. https://youtu.be/c06ATmj3J9s |
