| Jun 17, 2013 at 2:05 | comment | added | user968243 | I'm assuming that those graphs are graphs of loop gain, \$L(s) \equiv \beta A(s)\$. My book says that if the loop gain is positive at -180°, the system will be unstable. Have I misunderstood something? | |

| Jun 16, 2013 at 11:30 | comment | added | user968243 | Okay, let's suppose I were to place a pure 2kHz signal into the system. The system would be unstable wouldn't it? Is this system only stable because the non-2kHz signal would swamp the 2kHz signal? I don't really get why it would be stable... Are you suggesting it would be compensated to be stable? | |
