I am past the saturation issue, but my question is, i can only send and receive a sinusoidal flawlessly when i do 100 interpolation and 100 decimation. If I go less than that, why is my signal deformed (4 int 4 decm for example) . Also (according to the datasheet) Why do we need to make at least 4 int. and 4 decimation in USRP2? So please tell me some details about it. I know what interpolation and decimation, but cannot apply here? Does too less decimation (like 8) cause some overflow? So to summarize, can you please tell me the role of interpolation and decimation here and its critical values if any) and why there are these critical values. If I go like 4 interpolation and 40 decimation, the signal gets deformed, which I can understand, but why gaps between signal bursts? Also if I lower the signal under 100 decimation rate at the usrp2 receiver but also lower the interpolation rate (20 int 20 dec) my computer gets all blue and must stop the process (the graphic flows but the buttons on the graphic donÂ´t react) Regards dbeken -- View this message in context: http://www.nabble.com/Interpolation-Decimation-tp2...
