Hi I'm trying to get my system to work. The problem is the output from the initial 'minus' following the simulate signal is zero when it should be a value of 'signal - feedback'. I'm not very experienced with labview and I've attached my VI. Just wondering if someone could have a look and tell me how i can fix it. I've tried using selects and also the intializer terminal on the feedback node. the values for the inputs are on the front panel. Thankyou very much I've been stuck trying to work this out for a while
