Question

1 point Hz, causes no change Suppression of speech signal components above in intelligibility. Write exact answer in numeric value Your answer write answer in small lower case) letters. point In SSB signals, phase error in received signal shifts the phases of all spectrum by o resulting in distortion in quality of signal Write answer in small (lower case) letter

give one word answer as fast as possible

Answer 1

all all To generate (ov) obtain USB signal the filter should pass components above Wearvier unattenuated and com mpletely suppress componente below Warrier. This can't be done. The filter which can perform this needs to have ideal chara- cteristics. Hence we Seperate passband and stop band, The Voice signals fnherently provide this condition Hence Speech signale frequency componente below 300+12 important. 1 are not

from Weaver's method to autreutates that for Speech componente belowo 300HZ are generate SSB signale. the test signals the frequency in significant. This means that we may suppress all the speech componente below 300Hx without affecting the intelligibility appreciably
Answer for the first question is 300Hz

Second answer: Due to error the overlapping of signals takes place which is termed as "fading " it fades the quality of signal.
