"The digital phase modulation analysis based on the ëxperimental exploratory teaching model"

The digital band transmission system is similar to the digital base band transmission system, and the difference is that the digital band transmission has the presence of modulator and demodulator, the band transmission system include amplitude shift key control (ASK), the frequency shift key control (FSK) and the moving phase shift key control (PSK) in the binary, because of the psk error rate is relatively low, and the actual application is more extensive, For Vocational and Technology Education students, the process of signal modulation is more abstract, and the experimental exploratory teaching mode can improve the teaching quality and develop the signal analysis ability.
