Abstract
Provided is a transmission system including: a signal processing apparatusconfigured to transmit, via a signal cable, a delta-sigma modulated signal obtained by performing delta-sigma modulation on a transmission signal that is an RF signal; and a wireless apparatusconfigured to transmit, via the signal cable, a reception signal that is an RF signal. The signal processing apparatustransmits the delta-sigma modulated signal to the wireless apparatus, and the wireless apparatustransmits the reception signal to the signal processing apparatus. In the delta-sigma modulated signal, quantization noise is suppressed at the frequency of the reception signal. The reception signal is transmitted to the signal processing apparatuswhile the delta-sigma modulated signal is being transmitted to the wireless apparatus
