Quincey,
I am using Xcode 7.2. What version of Xcode are you running? Unless I am missing something, the version you typed into playground is not working for me in code editor when I press run.

This works in a playground:
func linconv<T: FloatingPointType>(signal_A signal_A: [T], signal_B: [T]) -> [T]? {
var arr = [T](count: 4, repeatedValue: T (0))
return nil
}
The point being that 0.0 isn’t necessarily convertible to an arbitrary FloatingPointType, but any FloatingPointType you’re likely to use will have a conversion init from an Int literal.
