Final answer:
Digital radio systems transmit data as binary ones and zeros, allowing for clearer transmission and compressed data. Analog modulation systems use amplitude, frequency, or phase modulation.
Step-by-step explanation:
One property that distinguishes digital radio systems from conventional analog modulation communication systems is that digital radio systems transmit data as a sequence of binary ones and zeros. This allows for clearer data transmission when the signal is weak and enables the use of computer algorithms to compress the digital data, allowing more data to be transmitted in each frequency range. In contrast, analog modulation systems modulate the amplitude, frequency, or phase of the wave to transmit information.
