• TI thinks resolved

What part would I need on order to demodulate an 18Khz frequency modulated signal (carrier) modulated at 500Hz to 7Khz?

Hi. I am seeking to discover whether TI has an analogue product that is suitable for demodulating an 18Khz frequency modulated signal that is modulated by an audio signal as low as 500hz and up to say 7Khz.. I'm contemplating whether the best approach is to use a Phase Locked Loop (PLL) IC. Thanks.
