Hello, I was wondering if pvstencil might be broken. I get no effect when applied and I've tried different combinations of parameters and table values. The signal passes through it completely unaffected. The syntax is: fsig pvstencil fsigin, kgain, klevel, iftable I've tried setting the kgain and klevel to all sort of combinations between 1 and 0, is this the valid range for the two parameters? Is it possible to use a generated table as the stencil table? Using GEN07? What would be the range of amplitudes? By using pvsbin and printing the amplitudes I found that the values ranged from 0 to around 28000, is that the range that the stencil table should have? I created a table with GEN07 and tested using different values but still no filtering is happening. Thanks! Hector
