If you have an RF (Radio Frequency) signal of 1MHz and you modulate it with a signal of 1kHz you end up with three frequencies 1MHz - 1kHz 1MHz 1MHz + 1kHz The carrier is 1MHz. The lower side band is 1MHz - 1kHz or 999kHz while the upper side band is 1MHz + 1kHz or 1.001MHz kHz is thousand cycles per second MHz is million cycles per second

What are the drawbacks of using amplitude modulation?
1)Lower frequencies, shorter range, smaller bandwidth. 2)More power required because, in amplitude modulation we are transmitting 3 frequencies i.e, carrier, lower side band and higher side band. the carrier have no any information but it required 2/3rd power. 3)The two side bands have same information so there is no need of transmitting the two side bands.
What does am frequency stand for?
AM stands for Amplitude Modulation. In theory, amplitude modulation could be applied to a radio signal on any frequency but the AM band on most domestic radios stretches from 530 to 1700KHz.
Is there any special IC for amplitude modulation?

What is the difference between a frequency modulator and a frequency mixer?
A mixer is a non-linear circuit that multiplies two signals together. If the inputs are sinewaves at frequencies f1 and f2 the output will contain signals at four different frequencies, f1, f2, f1 + f2, and f1 - f2. Some mixers may eliminate some of those outputs and post filtering can remove any other unwanted components. This is the way AM and SSB are typically generated. Modulation is a more general concept, and depending on the type of modulation you are doing, a mixer may or may not be involved in the modulation process.
What is amplitude modulation and frequency modulation and difference between them?
Both angle and amplitude modulation are involved in radio wavelength patterns. Angle modulation is where the modulating wave manipulates the angle of a sine-wave carrier. The two types of angle modulation include frequency and phase modulation. On the other hand, Amplitude modulation is the strength behind carrying the waveform in radio.

What is the range of modulation index in am?
The range of modulation index in amplitude modulation (AM) is typically between 0 and 1. A modulation index of 0 indicates no modulation, while a modulation index of 1 represents full modulation where the carrier signal amplitude varies from zero to peak value.
What is Modulation and what is the aim of modulation?
Modulation is any of several means of encoding an information carrying signal onto a carrier of fixed frequency. The purpose is to allow the information to be transported long distances.
Why do you need to do modulation?
In a radio system ... Modulation is applied to a carrier. If the carrier wasn't modulated it wouldn't carry any information other than that the transmitter was working. Not very useful. It is the modulation which contains the "information" which we want to send.
Why modualtion is need?
Without modulation, there's be no way to get any information onto a carrier signal. There are several different types of modulation schemes for radio carriers and almost as many different types demodulators to decode the information so that it can be converted into a usable form. For instance, AM (amplitude modulation), FM (frequency modulation), digital modulation, quadrature amplitude, etc.
How do you adjust the bands on a 1994 Dodge Intrepid?
The transmission in an Intrepid does not have any bands in it.
What are the contrast of amplitude modulation to frequency modulation?
AM (Amplitude Modulation) has a smaller bandwidth and can have more stations available in any frequency range. AM is cheaper and can be transmitted over long distances. FM (Frequency Modulation) signals are prone to interference due to physical obstructions. The better sound quality is due to a much higher bandwidth, using FM.

Is there any way to have scene yet descent for a catholic school hair?
Yes! you can put your hair in a scene side ponytail pull you hair to the side your bands are leave out some of your top layers on each side and tease the ponytail a little and your good.
What is the Digital modulation?
There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).
