Document Type and Number:
Japanese Patent JPH0831830
Kind Code:
B2
Abstract:
A multiple use radio frequency (RF) transmitter comprises means (2, 8, 22) for generating a plurality of different digital information signals and means (12) for generating respective digital carrier signals for said information signals, said carrier signals having higher frequencies than their respective information signals. Further included are means (10) for modulating said digital carrier signals with their respective digital information signals and means (24) for accumulating said modulated signals to a composite digital signal. Digital-to-analog converter (DAC) means (26) are common to each of said modulated signals for converting said composite digital signal to a composite signal in analog format. Further provided are means (30) for altering the frequency of said composite signal to a desired radio frequency (RF) band and means (32) for excluding frequencies outside said desired RF band from said composite signal.
