Hello and Thank you for your help,
Alright I have a group project for my physical layers of communication class in which it appears I will be forced to do all the work. Basically we have to build a simple modulator. Basically we have a digital signal that delivers a bit every 60 msec and a carrier frequency we are going to put through a voltage divider to get frequencies to represent the 1's and 0's. What I am trying to find is something that can be used to look at the digital signal and based on if it's a 1 or 0 switch between the low or high frequency inputs we have. Our professor suggested we look into double pull single throw relays or digital gates, but I have had little luck on that front. The problem with school is that all they teach us is theory then expect us to actually complete a real world assignment so any help would be greatly appreciated thank you for your time.
