A 10-MHz sinusoidal carrier wave of amplitude 10 mV is modulated by a 5-kHz sinusoidal audio signal wave of amplitude 6 mV. Find (a) the frequency components of the resultant modulated wave and (b) ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Have you ever heard terms like modulation scheme, orthoganal frequency division multiplexing (OFDM), or symbol rate and scratched your head? As new wireless standards emerge, we get excited about the ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...
