I'm trying to simulate tut3 by putting in a sine-wave at the input and looking at the output of the accumulators - the acc_length is 2 and FFT and pfb size is 12. Input parameters for the sine wave are:
Sample based, Simulation Time Amplitude 0.1 Bias 0 Sample per period 100 number of offset samples 0 sample time 1/4 Interpret vector parameters as 1-D checked I only look in the region where the output valid flag is high - The problem is that I get a forest of lines out of both accumulators with no obvious spike where the signal should be. It doesn't look like there is clipping. I can post pictures of the scopes if needed but I'm just wondering if I'm missing something obvious? -- Ross Williamson Research Scientist - Sub-mm Group California Institute of Technology 626-395-2647 (office) 312-504-3051 (Cell)
