    Noise input form file for vsource Reply

    Hello

    I had two questions:

    1) Can I enter formula (e.g. one as below) in the noisefile that I want to be included for defining the noise source. I am asking this becuase when I tried it, I got errors but when I entered the same thing in via Noise/Frequency points in the vsource Object properties, it ran fine. But it has limitation of 10 pairs only. Does the file input also has some such number-of-pairs limitation?

    fpfd*0.05 propsdnoise_multfac*((2*sin(pi*0.05))**(2*modord-2))

    fpfd*(10**(log10(0.05)+0.1)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.1))))**(2*modord-2))

    fpfd*(10**(log10(0.05)+0.2)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.2))))**(2*modord-2))

    fpfd*(10**(log10(0.05)+0.3)) propsdnoise_multfac*((2*sin(pi*(10**(log10(0.05)+0.3))))**(2*modord-2))

     

     2) As you can see in the example above, I am trying to do the logarithmic interpolation. Is it possible to do that automatically as this interpolation is still not good enough as what is happening is I calculate logarithmic interpolated value by the equation aobve but the points between them are interpolated linearly inside the simulator. Is there any solution to it?

     

    Thanks.

    Even if its not possible, a simple reply saying that would be very helpful as it will help me stop 'futile' attempts at trying to find a way out.
