Hi,
	I am trying to find some info on the latest generation of
	cordless telephones ( not celluar ).  Some of the new
	models I'm seeing pop-up in the stores indicate that they
	have "digi-clear" circuitry or other such "technology".
	  Do they mean that the actual signal format between the
	base-set and the handset is digital ? ( QAM , PSK , or ASK )
	Or is it just some type of filtering done before conventional
	AM or FM transmission.  This brings another querstion ! Do
	cordless phones use AM or FM transmission ?  
	  Any help appreciated.
				Thanks,
				   Dan Bazinet
