We're thinking of sending a wideband (say, dc to 50 MHz) signal using FM. The carrier could be in the 500 MHz to 1 GHz range maybe.
I can get the VCO. What's a good way to do the FM discriminator these days?
I could homebrew a quadrature detector, with some resonator and an XOR gate or a mixer, but there must be some easier way to do it. Not being an RF type, I'd appreciate suggestions.
