I need to be able to demodulate a frequency modulated 18Khz carrier. Does Analogue Devices have a product that can be used to do that? It is anticipated that the 18Khz signal, may be modulated at say 500Hz or 1Khz discrete steps up to about 3.5Khz or 7Khz. Thanks.
EDIT: Would demodulation by a PLL be in the ballpark?
