Good day to all,
i have some question regarding the y-axis in usrp_fft.py… it is
in unit dB. so how does it convert from ADC value to dB? the output from
after c2mag block we got the magnitude value of the power isn’t it? so
does from the ADC value it convert to the power? what is the formula?
second, what is this formula mean?
log = gr.nlog10_ff(10, self.fft_size,
this is to convert from power in magnitude domain to dB… is it? what is
actual formula on this? thank you very much in advance
