Hi;
I'm doing a project for spectrum analyzer; i did analog parts ( now i have 0-100 Mhz analog signal ready for sampling).
I wanna show the spectrum in a LCD( i had wrote the code for that in last).
My Question is that :
am i have to convert it to Digital and then take an fft from it and then send the data to LCD???????
if yes! am i need 2 ADC for real and imaginary part ???
and
if my ADC have the resulation of 10 bit then what size of FFT should i use?
any one have any idea to help???
thanks
