Etc channel frequency? 

which is better AM or FM and why?

with this is a sudden voltage spike bad motor, etc. can amplify the carrier signal and cause glitches.FM Frequency Modulation works by increasing and decreasing the carrier signal frequency by a little bit ex is then decoded by the receiver to recover the original sound.Each AM channel is assigned a range of frequencies, typically about 10 kHz wide. The common frequency identification such as AM 1190 for America AM 1190

What is Spread spectrum

hi roshank!Spread-spectrum techniques are methods by which energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth://en.wikipedia.org/wiki/Spread spectrum...well;Spread spectrum is a form of wireless communications in which the frequency of the transmitted signal is deliberately varied. This results in a much greater bandwidth than the signal would

What is Wi-Fi 802.11?

and Electronic Engineers at http://grouper.ieee.org/groups /802/11/.The 802.11 Wi-Fi ChannelsThe most common 802.11 specification, 802.11b, defines twelve channels. These channels utilize overlapping frequencies spectrum signaling method DSSS. 802.11a uses the 5 GHz U-NII band, which offers 8 non-overlapping channels rather than the 3 offered in the 2.4GHz ISM frequency band.The segment of the radio frequency

CDMA

of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency UHF cellular telephone systems with the transmitter frequency. There are trillions of possible frequency-sequencing codes, which enhances privacy and makes cloning difficult.The CDMA channel is nominally 1.23 MHz wide. CDMA networks use a scheme

How can broadband internet connection is made to both the computers which are in networking?

how does broadband work? The online Websters dictionary defines broadband as "A class of communication channel capable of supporting a wide range of frequencies, typically from audio up to video frequencies. A broadband channel can carry multiple signals by dividing the total capacity into multiple, independent bandwidth channels, where each channel operates only on a specific range of frequencies

Channel

channels refer to particular frequencies at which radio waves are transmitted. IRC channels refer to specific discussions. For the UK Shipping Forecast the English Channel is divided into the areas of from to particular frequencies at which radio waves are transmitted. IRC channels refer to specific discussions. 3 In sales and marketing, the way in which a vendor communicates with and sells products to consumers. 4

in which frequency range does cellular phones operate?is the range worldwide or specific only to india or is worldwide?

of frequencies that can use, there are different ranges available.This range is split up into channels of separate frequencies. There are some control channels which are used to identify phones and to getA high frequency ringtone, known as Teen buzz is a tone too high for most adults to hear, making it a popular ringtone for teens who want to evade classroom rules by sending and receiving text

What do you mean by 3 dB cutoff frequency? Why is it 3 dB, not 1 dB?

channel....well, In electronics, cutoff frequency or corner frequency is the frequency either above which or below which the power output of a circuit, such as a line, amplifier, or electronic filter frequencies of a communication channel. In the case of a waveguide or an antenna, this corresponds to the lower and upper cutoff wavelengths respectively. the 3dB cutoff frequency of a signal spectrum

What is GSM 900 ?

direction downlink, providing 124 RF channels channel numbers 1 to 124 spaced at 200 kHz. Duplex spacing of 45 MHz is used.In some countries the GSM-900 band has been extended to cover a larger frequency extended to cover a larger frequency range. This extended GSM, E-GSM, uses 880915 MHz uplink and 925960 MHz downlink, adding 50 channels channel numbers 975 to 1023 and 0 to the original GSM-900 band

Is there an equation for coverting Hz Hertz into Mbps mega bits per sec?

be represented by a bunch of sinusoidal waves an infinite series of discrete sinusoidal waves with a base frequency equal to the square wave frequency and even and odd harmonics, which are multiples of the base frequency. They comprise the frequency spectrum.At minimum, one of these sinusoidal waves, the third harmonic 3 X 33 MHz = 100 MHz, must be transmitted for a reliable Ethernet transmissions.For it can also

What is UHFUltra High Frequency. ?

Ultra High Frequency The range of electromagnetic frequencies from 300 MHz to 3 GHz. In the U.S., analog television has used UHF channels 52 to 69 in the 700 MHz band. Because of the transition from frequencies often used to broadcast television signals. Mobile phones and satellite radio also use UHF signals. The letters UHF stand for: Ultra High Frequency.UHF FrequenciesAny radio frequency between 300

WHAT IS BAUD AND BAUD RATE?

serial communication signal changes states; a state being either a voltage level, a frequency, or a frequency phase angle.If the signal changes once for each data bit, then one bps is equal to one baud rate the more data the device can transmit per second, typically in a binary channel the baud rate is equal to the bit rate, therefore 1 baud = 1 bit a second....The baud rate of a data communications
