Frequency Scale Conversion
From f To f Scale
frq2mel mel2frq mel The mel scale is based on the human perception of sinewave pitch.
frq2erb erb2frq erb The erb scale is based on the equivalent rectangular bandwidths of the human ear.
frq2midi midi2frq midi The midi standard specifies a numbering of semitones with middle C being 60. They can use the normal equal tempered scale or else the pythagorean scale of just intonation. They will in addition output note names in a character format.

11-OtherLinearTechniques
Differential PSK (DPSK)
Inexpensive
Quadrature Phase Shift Keying (QPSK)
Twice as spectrally efficient than BPSK
Offset QPSK (OQPSK)
reduce envelope variation
π/4 QPSK
reduces envelope variations to a lesser extent
than OQPSK can be noncoherently detected

说明： 设计一个理想通信系统，实现信息字符流的传输。
发射器：
<1>将消息（字符串形式）编码成一个符号序列；
<2>用脉冲成形将串符号序列转变成模拟脉冲信号；
<3>将模拟脉冲信号调制到载波信号上。
接收器：
<1>对接收的信号进行采样；
<2>解调信号成基带信号；
<3>将信号恢复成字符串。(Design an ideal communication system, the realization information transmission of character flow.
Emitters:
< 1 > will news (string form) coding into a symbol sequence
< 2 > by using a pulse forming will string of symbols into a simulation pulse signal sequences
< 3 > will simulate the pulse signal modulation to carrier signal.
Receiver:
< 1 > of received signal sampling
< 2 > demodulation signal into baseband signal
< 3 > will signal back into a string.)
