提供一個115赫茲時每八度6分貝的低頻上移濾波器。 -
Because msk phase is continuous, the rolloff velocity of the msk spectrum to the psk was improved greatly. on the other hand, if the channel ' s bandwidth is presented, the data transmission rate of msk is better than that of bpsk. 2
由於msk相位連續，它相對于psk頻譜的滾降速度有了很大的改善；另外在給定通道頻帶的時候，它比bpsk傳輸的數據速率高，每秒能傳輸更多的比特。
