[Hackrf-dev] Low pass filter lesson 1

[Matteo Terzi]

Hi all,
I'd like to know why does Micheal Ossmann use a Low Pass Filter in the
Lesson 1 (https://greatscottgadgets.com/sdr/1/ --> minute 22:00).
He says that in that way just frequencies near to the zero Hz can pass but
it doesn't make sense....how radio frequencies can pass if they have a
value of MHz??
Thanks

Matteo
