The bandpass filter is being told to operate at a sample rate of 7K, but in fact the samples are coming from a USRP with decimation=256, which gives 250KHz sample rate. The filter bandwidth is *quite* narrow, so if it was told the correct sample rate, it would likely distort that signal even more. As previously observed, the throttle blocks are quite unnecessary. Also, why the "repeat" block? The file source is already set to "repeat", so I don't understand what that repeat block is doing there. |
