Text of the note
Show as plain text (Turkish; formulas and drawings are not included)
in B Bandwidth kTB
N_i : input referred total noise
Receiver noise Floor
F Noise factor, k Boltzman constant, T temperature
Receiver SNR & Noise
output noise = input Noise + N_A
Calculate NF total
Calculate Noise floor ( B = 5 MHz)
Sensitivity and Dynamic Range
Sensitivity is the minimuminput signal which can be detected with the acceptable output SNR.
P_sig,in(min)|_dB = noise floor_dB + SNR_out,dB
A GSM receiver has SNR_out(min) = 12 dB
channel BW = 20 khz
what is the minimum acceptable signal power ?
Spur-free Dynamic Range
