Which one of the following is not correct in wireless network or transmission?

a.Digital transmission cannot be used without converting bit-stream into analog signal.
b.Digital modulation translates digital data (bit-stream) into analog baseband signals.
c.Analog modulation shifts the center frequency of baseband signal up to the radio carrier.
d. Analog modulation converts the analog baseband signal to digital data.

d. Analog modulation converts the analog baseband signal to digital data.

Analog modulation does not convert the analog baseband signal to digital data. Instead, it shifts the center frequency of the baseband signal up to the radio carrier, enabling it to be transmitted wirelessly.
