15. ated SNR or S N is a measure used in science and engineering that compares the level of a desired signal to the level of background noise It is defined as the ratio of signal power to the noise power A ratio higher than 1 1 indicates more signal than noise While SNR is commonly quoted for electrical signals it can be applied to any form of signal such as isotope levels in an ice core or biochemical signaling between cells The ratio is usually measured in decibels dB Answer i The signal to noise ratio the bandwidth and the channel capacity of a communication channel connected by the Shannon Hartley theorem In digital communications the SNR will probably cause a reduction in data speed because of frequent errors that require the source transmitting computer or terminal to resend some packets of data SNR measures the quality of a transmission channel over a network channel The greater the ratio the easier it is to identify and subsequently isolate and eliminate the source of noise 1 Some testing program which is base on TCP IP protocol such as FTP Iperf NetIQ the Cause bandwidth of testing outcome will be limited by TCP window size i L Some operating system limited the maximum bandwidth such as windows series OS Werecomwiend in est VSL best by crmartit eamall eck ono Pou Solution don t have Smartbit we recommend test that by IPERF program and
