                IMPORTANCE IN QUALITY MEASUREMENT





                                        HIGHER SNR, BETTER QUALITY


                                            A greater SNR denotes a signal that is

                                            significantly stronger than noise, which makes
                                            transmission or reception is clearer and more
                                            reliable.

                                       APPLICATIONS



                                           A higher SNR means fewer errors in data
                                           transmission.











                                       IMPACT ON DATA RATES AND
                                       BANDWIDTH

                                            SNR has a direct impact on the highest
                                            achievable data rate in digital communications.

                                            The Shannon-Hartley theorem states that the
                                            bandwidth and SNR are related to the channel
                                            capacity  in bits per second.
