2.ASK Modulation principle

        Amplitude keying , Remember to do ASK, Or switch keying ( On-off keying ), Remember to do OOK . Binary digital amplitude keying is usually recorded as 2ASK. For linear modulation such as amplitude keying , In binary ,2ASK Is the use of representative digital information “0” or “1” Baseband rectangular pulse de keying a continuous carrier , Make the carrier output intermittently , When there is carrier output, it means transmission “1”, No carrier output indicates transmission “0”. According to the principle of linear modulation , A binary amplitude modulated signal can represent the product of a unipolar rectangular pulse sequence and a sinusoidal carrier .

       2ASK The signal can be expressed as :

3.ASK Modulation process FPGA Realization

        Through the above analysis , We can know in FPGA in , Realization ASK Mainly involves cos Signal generation , Binary digits and cos Signal multiplication station
