Can intelligence be sent without a carrier?
Can intelligence be sent without a carrier? The intelligence signal is generally a low frequency signal. So, it cannot be transmitted for a long distance by using antenna due to low frequency. But it can be transmitted directly by using wires. Why is carrier frequency higher than message frequency? To increase the energy of the […]
