Which part of the sine-wave expression cannot be varied in accordance with the low-frequency intelligence to create a modulated signal?
In a sine-wave expression, the amplitude, frequency, and phase can be varied to create a modulated signal in accordance with low-frequency intelligence. However, the carrier wave's frequency itself cannot be varied; it remains constant and serves as the baseline for modulation. This ensures that the carrier maintains its identity while the modulation conveys the desired information.
What else can I help you with?
Why is the intelligence signal not in the AM envelope?
The intelligence signal is in the AM envelope.In AM modulation, the carrier is amplitude modulated by the signal. This signal appears as the envelope of the carrier. You can demodulate it by following the peaks on each cycle of the carrier. You can either follow the positive peaks or the negative peaks - it does not matter if the original modulation is symmetrical.
Why analog data have to be modulated onto an analog signal?
For transmission through a radiowave.
Are digital transmissions modulated over a carrier?
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier
What is FM transmitter and what are the different FM transmitters?
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
What are two essential components of a modulated wave?
amplitudefrequencyphase
What is bw equals usb-lsb?
That's the expression for the total RF spectrum occupied by a modulated carrier.
