…On the other hand, when the modulating signal is digital, phase modulation is quite different from frequency modulation. Digital phase modulation is called PSK (short for phase shift keying), and is called 2-phase when the modulating signal is 2-value, 4-phase when it is 4-value, and 8-phase when it is 8-value. In the case of 2-phase, 1 bit can be sent, in the case of 4-phase, 2 bits can be sent, and in the case of 8-phase, 3 bits can be sent per modulation time interval (time slot). …

Japanese:

…一方,変調信号がディジタルである場合,位相変調は,周波数変調とかなり異なったものである。ディジタル位相変調は,PSK(phase shift keyingの略)と呼ばれ,変調信号が2値の場合2相,4値の場合4相,8値の場合8相という。1変調時間間隔(タイムスロット)当り,2相の場合は1ビット,4相の場合は2ビット,8相の場合は3ビット送れることになる。…
