The modem is modulated by the transmission side converts the digital signal into an alog signal by the demodulation at the receiving end converts the analog signal to a digital signal to an apparatus. This procedure using VHDL language, the realization of a binary amplitude shift keying (2ASK) modulation and demodulation binary frequency shift keying (2FSK) modulation and demodulation, binary phase shift keying (2PSK) modulation and demodulation process.
