Increasing SNR and Dynamic Range using Oversampling

WebThis is not possible. The input noise will be amplified just as much as the signal. Plus, some additional noise will be added by our amplifier. So the overall effect is the output SNR is lower than the input SNR. (This is why the NF is positive when expressed in dB) But we want the SNR to be reduced by as little as possible. Share Cite Follow WebAn LNA is useful to help lower the noise figure of a radio system which results in higher SNR values (especially at the UHF and higher bands), and can be used to overcome losses in the signal chain from components like coax cables and connectors.
