AMPModem

Modulates or demodulates AM, USB or LSB

 class AMPModem {
        constructor AMPModem('name');

        bool configure( {'modulation_index' : number, 'type' : 'AM' OR 'LSB' or 'USB', 'agc' : boolean });

        IQData  modulate( FloatData input );
        FloatData demodulate( IQData iq ); 
 }

This object can be used with the Digital Down Converter
Note that the demodulator does not handle the AGC process. Again, see Digital Down Converter for integration.

.configure

Sets the configuration for the AM/SSB modem.
- Parameter modulation_index is valid in the range [0..1] and is used for modulation only.
- Agc parameter is only valid for demodulation

Example : 

var amdemod = new AMPModem('myname');
amdemod.configure( { 'type' : 'AM' , 'agc': true } ) ;

for( ; ; )  {
    var IQ = ...
    var audio = amdemod.demodulate( IQ );
    ...
}

.modulate

.demodulate
