Ohh... bandwidth is just half the sample rate of course. So the cutoff has to be 50k and transition 20k for example. Am 21.07.22 um 10:45 schrieb Fabian Schwartau: Hi Isaac, I am not sure what you are trying to achive. However, your low pass filter seems to be set up incorrectly. You have a s

Hi Isaac, I am not sure what you are trying to achive. However, your low pass filter seems to be set up incorrectly. You have a signal with 1MHz and 10MHz samplerate. Your low-pass filter has a cutoff at 5MHz and then down-samples by 100. If you want to make sure that there are no frequency c

Hi Isaac - it sounds like there's a beat frequency - probably between the pulsed signal and the second freqency. I'm assuming you didn't see the problem in the pulsed signal signals. -- Cinaed The definition of the beat freuency is the absolute difference between two frequencie. On 7/20/22

Hello everyone My name is Isaac. I'm dealing with a curious behaviour that I can't understand... I'm generating my pulsed signal by multiplying a vector source and a signal source. Then I'm multiplying this pulsed signal with a continuous signal source at the same frequency, passing then for a lo
