Hello Kevin,
I tried a similar example with lower frequency with Gnu-Octave and LTspiceXVII. Both showed exactly this artifact near 0.55ms. The results have been identical.
?
Changes to the schematic for a shorter simulation.
V1: 1.2
V2:? PULSE(1 -1 0 1m 1m 1u 2m)
.tran 0 1m 0 10n
Bv (no change)
V=sin(2*3.14159262*v(fr)*time*1000000)
Octave:
>> t=0:100000;
>> t=1e-8*t;
>> m=0:100000;
>> m=2.2-2e-5*m;
>> y= sin(2*3.14159262.*m.*t*1000000);
>> plot(t,y)
Best regards,
Helmut
