Abstract

DC60 (10/08/44) FM broadcast transmitter transmits a broadcast signal that has a carrier frequency. And sidebars for broadcasting, can be transmitted with full power within the band width. For transmissions with values close to the Pah wave. It is incorporated by a modulated FM stereo source that has a broadband frequency and has a strong sidebar. The band width is less than the band width of the transmission that represents the stereo signal. Such things are also included. With the IBOC signal source that is also modulated, there are pulses of the Are spaced in a relative way to represent the IBOC digital signal encoded in Encoded signal characteristics, variable pulse width and underlying band width. In the transmission band width that does not overlap the sidebars of the FM stereo signal, the integrator combines the modulated signal and the modulated IBOC signal to make There was a signal that was broadcast. The FM broadcast receiver receives the broadcast signal incorporated. First modulated, showing an FM stereo signal and a second modulated signal, which There are pulses of PAH waves that are spaced in a relative way to represent the information signal. In-Band-on-Channel Digital (IBOC) that is encoded as a width-encoded signal. Of variable pulses It is incorporated with a splitter to generate a more accurate signal. Isolated one showing the FM stereo signal and the second split showing the signal. IBOC digital data. The FM signal processor generates a stereo sound signal that is It is expressed by an FM stereo signal. The IBOC signal processor generates the information signal. Digital as it is expressed by IBOC digital signal. The FM broadcast transmitter transmits the broadcast signal that contains the carrier frequency at And sidebars for broadcasting, can be transmitted with full power within the band width. For transmissions with values close to the Pah wave. It is incorporated by a modulated FM stereo source that has a broadband frequency and has a strong sidebar.
