TRANSMITTING RF SIGNALS EMPLOYING IMPROVED HIGH-LEVEL COMBINATIONS OF ANALOG FM AND DIGITAL SIGNALS |
摘要 |
<p>Apparatus and method are presented for broadcasting an RF signal comprised of analog FM and digital signals. An analog FM source provides an analog FM signal. A digital source provides a digital signal. A splitter splits the FM signal into a fractional portion and remainder portion. A summer combines the fractional portion with the digital signal to provide a first combined signal. A main FM transmitter amplifies the remainder portion to provide an amplified FM signal. A digital transmitter amplifies the first combined signal to provide an amplified combined signal. A combiner combines the amplified FM signal and the amplified combined signal to provide a composite RF signal to be broadcasted. -20-</p> |
