In the analog world, if a signal is just 1 voltage then it must be a real function. But it's also possible to represent a complex function as an analog system with two voltages, as in an IQ mixer. | |

Pls allow me ask further.What 's the difference between real sine function and complex sine function?In real radio world,do we have real sine signal?
