Explain what is modulation?

In this part of the presentation can you give me a narrow explanation of these:

It's simply the proportion of the actual frequency deviation to the maximum frequency deviation. Select your answer. Carrier swing Percent modulation Phase deviation Frequency deviation

Answer the question quecly please Electronic lab

It is a circuit in which the carrier is varied in such a way that its instantaneous phase is proportional to the modulating signal. Select your answer. Discriminator Phase modulator Frequency modulator Detector

Briefly explain why in the digital transmission of sound in radio systems, an analogue to digital converter required at the transmitter and a digital to analogue converter is required at the receiver.

Figure (1) shows the block diagram of a wideband frequency modulator using the indirect method. This modulator is used to transmit audio signals containing frequencies in the range of 100 Hz to 15 kHz. The narrowband is supplied with a carrier of frequency fl-0.1 MHz by crystal- controlled oscillator also ß-0.2, a second crystal- controlled oscillator supplied a sinusoidal wave of frequency 9.5 MHz to the mixer.

Solve the following problem in detail:

Type your question here The figure below shows a satellite receiver uses two hytrodyne operations. It is used to receive transmissions at 136 ???. the first local oscillator operates below the incoming carrier frequency, while the second operates above the first IF frequency. Find all possible image frequencies.

Consider the following plots of time-domain and frequency-domain signals. Label the axes of the five plots. For example, plot B should be labeled as amplitude vs. time. Characterize each plot as either a time-domain or a frequency-domain signal. Describe the mathematical relationships among the plots. For example, how could you arrive at plot A from plots D and E?
