Frequently Asked Question on Modulation
How does Modulation affect Bandwidth?
Modulation can change the bandwidth of a transmission. For example, AM and FM signals require different bandwidths. In general, higher modulation rates and more complex modulation methods require larger bandwidths.
What is the Modulation Index?
The modulation index is a measurement of the degree of modulation in a modulated signal. It quantifies the amount by which the modulating signal modifies the carrier signal.
Which device is used for Modulation and Demodulation?
The modem is the device that is used for modulation and demodulation. Modem is the process of converting analog signal to digital signal and vice versa. It can modulate and demodulate the signals of each other.
What is Modulation?
Modulation can be digital or analog, the input wave of the analog signal varies continuously like a sine wave. Modulation can be defined as the process of converting data into waves by adding information to a carrier signal. Such a signal can be transmitted electronically or optically, but it must have a consistent waveform.
