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.
For transmission through a radiowave.
yes for transmission of the signal to take place smoothly,digital tranmission needs to be modulated over a carrier

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.
That's the expression for the total RF spectrum occupied by a modulated carrier.

AM = amplitude modulated. FM = frequency modulated.
a. velocity modulated tube b. frequency modulated tube c. Amplitude modulated tube d. simple triode
FM means Frequency Modulation.
It gives frequency modulated signal
am is amplitude modulation, fm, frequency modulation
For transmission through a radiowave.
