降采样(16Kto8K)

语音传输的实验程序:不同编码方式图形比较画出线性A律CVSD在相同随机错误与突发错误参数下得译码后波形并加以比较。以下实验若未注明均采用该参数设置：幅度：6V     频率：1K   编码位数：不同不同编码方式下 不同的误码率以及相应的传输速率 

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for

This program will ask how many numbers you want to find the average of, then it will allow you to enter your numbers(yes they can even be decimals) then it will calculate the mean, median, mode and range of what you enter.
