How to Select the Cutoff Frequency of Your Low-Pass Filter
You may not want a cutoff frequency of 10 kHz because this would apply almost 2 dB of attenuation to the 7.5 kHz signal: In this case it would be better to increase the cutoff frequency until 7.5 kHz is closer to the almost-flat section of the passband. For example, if you push the cutoff out to 20 kHz, the attenuation at 7.5 kHz is less than 0 ...
