WHAT IS BAUD AND BAUD RATE?

or modulation rate; the number of distinct symbol changes signalling events made to the transmission medium per second in a digitally modulated signal or a line code. The baud rate is related to but should second. In case of a modem, this corresponds to 1,000 tones per second, and in case of a line code, this corresponds to 1,000 pulses per second. The symbol duration time is 1/1,000 second = 1 millisecond

what is use of modem in computer ?

send in a given time, normally measured in bits per second, or "bps". They can also be classified by Baud, the number of times the modem changes its signal state per second.Baud is NOT the modems speed. The baud rate varies, depending on the modulation technique used. Original Bell 103 modems used a modulation technique that saw a change in state 300 times per second. They transmitted 1 bit

Create a menu driven program under main menu Ari oper, submenu add,subtract ,multiply , division & exit. Here the two integer numbers will be taken as input

well Rakesh, You need three variables, one for the first number of type doubleto hold large numbers. one for the second number, and of course one for the sign, or type of calculation we are doing.Dim first As DoubleDim second As DoubleDim sign As StringPrivate Sub Command1ClickIndex As IntegerIf txtDisplay.Text = "" ThentxtDisplay.Text= Command1Index.CaptionElse txtD isplay.Text= txt

Clock Cycle

well, In a computer, the clock cycle is the time between two adjacent pulses of the oscillator that sets the tempo of the computer processor.The number of these pulses per second is known as the clock speed, which is generally measured in Mhz megahertz, or millions of pulses per second and lately even in GHz gigahertz, or billions of pulses per second.The clock speed is determined by a quartz

A voice signal sample is stored as one byte. Frequency range is 16 Hz to 20 Hz. What is the memory size required to store 4 minutes voice signal

Its 1920Bytes. As the bandwidth f2-f1 is 20-16=4Hz. The sampling frequency should be twice the bandwidth 2B. the sampling frequency is 8Hz= 8 samples= 8 cycles/second.4 minutes=460 =240 Seconds1sample->1 Byte1Second->8 Samples240 Seconds->2408 = 1920 Samples...Well Navraj , you need to calculate it.The exact answer would be "15 MB"Usually voice Signals consume more space

The baud rate varies, depending on the modulation technique used. Original Bell 103 modems used a modulation technique that saw a change in state 300 times per second. They transmitted 1 bit for every baud, and so a 300

what is wi fi??????

second. It also uses orthogonal frequency-division multiplexing OFDM, a more efficient coding technique that splits that radio signal into several sub-signals before they reach a receiver. This greatly transmits in the 2.4 GHz frequency band of the radio spectrum. It can handle up to 11 megabits of data per second, and it uses complimentary code keying CCK coding.802.11g transmits at 2.4 GHz like 802.11b

WT IS AVG. NOTup toSPEED by using BSNL Int Connect Card CDMA2000IXbased [2 TYPE NIC&EVDO Card

].BSNL CLAIM up to 144Kbps.my loc.isroorkee-hardwar-uttrakan d...the BSNL claimed 144Kbps is the average internet connection speed/bit rate which is normally measured in kilobits per second. Which means your Int Connect Card is capable of sending 144kb in one second. While your ISP and modem manufacturer talk in kbps - for example your card may be a 144Kbps modem - many browsers and ftp programs

What is a modem?

in terms of bits per second bps. The fastest modems run at 57,600 bps, although they can achieve even higher data transfer rates by compressing the data. Obviously, the faster the transmission rate per second modem that could carry e-mail has become obsolete. 14.4 Kbps and 28.8 Kbps modems were temporary landing places on the way to the much higher bandwidth devices and carriers of tomorrow. From

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

The Hertz is often used as a unit in the measurement of data transfers.A Hertz is one cycle per second. A cycle is a single occurrence of a periodically repeating phenomenon. For example, one sinusoidal wave.A communications waveform may have a repeated shape. For example, the Ethernet can be measured in cycles per second Hz.Roughly speaking, and for measurement purposes, it can be considered a

What are tri-state devices and why they are essential in a bus oriented system?

Tri-state devices having exclusive gate output control include a tri-state device having first and second inputs and a tri-state output, a normally-off transistor connected in series between the tri-state output and a first reference potential e.g., VCC or VSS and an exclusive gate e.g., NOR, OR having first and second inputs coupled to the first and second inputs of said tri-state device, respectively

which is better AM or FM and why?

my explination the reason why the signal is "clear":All RC radios send out sine waves at 75MHz or 27MHz 75 million waves per second or 27 million waves per second This is you carrier signal;kHz" represents a kilo Hertz, or 1000 oscillations per second. The AM Amplitude Modulation method involves the encoding of the original sound through modulating or changing the amplitude of the radio signal, which
