What happens when a stronger signal and a weaker signal both overlap at the same frequency in frequency modulation?
If one signal is weaker and the other is stronger, the receiver captures the stronger signal and completely ignores the weaker one, resulting in adequate reception.
What is input output technology for multimedia?
Iput: This is the act of entering information. For example when you type a word each letter is made up of numbers: one's and zero's. Now those one's and zero's are translated into the actual word you typed and you can now see the word in the screen hance the Output.
How do you make electricity into the computer?
A computer operates by working with pulses of electrical energy. Depending on the voltage of the pulse, it represents either a zero or a one. Electricity is also need to spin the disc drives.
Why using fios does your telephone voice communication shore the fiber optic cable with internet data?
The services are able to share the same data cable - because each separate signal is sent in 'packets' of data - each with its own security tag - to stop cross-over from one to the other.
Why is digital technology preferred to analog technology in communications technology?
Why digital communications and what its advantages over analog communication ,first you have to know what is the difference between analog signal and digital signal. Analog signal analog signal is continuous time signal i.e. it has a value at any moment of time and it has infinite number of valus , such as dinusoidal signal ,you can substitute X with any value and you will have an value in Y in the follwing sin relation Y=sin(X). 1-Noise and destortion immunity:-when analog signal is transmitted in free space for long distances it will be distorted and no an ideal recovery done in receiver to recover the exact signal which transmitted ,but in digital communication digital signal consist of 2 levels only zero or one (not like the analog one , it has infinite numbers of values or levels at each period of time),so digital signal can be recovered easily and excactly like transmitted one. Hint : Device that used to pattially recover the analog signal after a certain distance is called repeater ,from its name it receives transmitted analog signal and filter it and amplify it and transmitt it),but in digital transmission it is different ,the device used for recovering digital signal which transmitted from acertain distance is called regenerative repeaters ,it receives transmitted digital signal and recover it to regenrate a new exact signal like received one then retransmitt it for further distance. 2-More privacy and security due to encryption. 3-Error detection techniques can be used and correction as well. 4-Easy for processing and applying multiplexing techniques. 5-Low cost. 6-Transmission rate can be changed easily. 7-Digital hardware implementation is flexible and permits the use of micrprocessors, digital switching elements and layer scale.

What is a zero-order hold?
A zero-order hold is a mathematical model of the practical signal reconstruction done by a conventional digital-to-analogue converter, describing the effect of converting a discrete-time signal to a continuous-time signal by holding each sample value for one sample interval.
What is One's compliment in binary numbers operation?
This is an operation in which each zero is changed to a one, and each one is changed to a zero.
Which number represents the value of the base in every number system?
10 (that is, one zero, not ten).
What does one and zero mean in binary form?
The binary number 10 represents the number 2
What is the difference between BPSK and QPSK?
Binary PSKQPSK.1. Two different phases are used torepresent two binary values.1. Four different phases are used to represent two binary values.2. Each signal element represents only one bit.2. Each signal element representstwo bits
What are five multiples of zero?
Each one of them is 0.
How many meters long is a wavelength that measures 10 squared m?
Wavelength is a measure of distance not area. It is the distance traveled by a signal from a Zero state to a Plus One state back through Zero to Minus One and returning to Zero.
Why do we equate each factor to zero?
The product of a number of factors can be zero only if one of them is zero.So, if a given expression is zero, you factorise it and then, by the above rule, the statement is true if any one of the factors is zero. You therefore set each factor equal to zero to find the different possible solutions.
What represents one year of growth on a tree ring?
On the stump of a tree, each line represents one year of growth on the tree ring.
How does a tally chart help you to display data?
Each one. On A tally chart represents 1 Each. Number Represents 5 make. A tally chart
Each cell of a punnett square represents one possible?
genotypic
How does analog work?
There are many types of analog systems, but the one thing that they all have in common is that a signal voltage represents some physical quantity.One of the simplest examples might be a guitar and amplifier: the electromagnetic pickup on the guitar produces a voltage that represents the motion of the strings. The amplifier first increases the magnitude of that signal, and then its power. The electrical signal is then used to drive an electromagnetic loudspeaker which changes the signal back into physical vibrations. At each stage, the variation in signal voltage is analogous to a physical vibration.This is in contrast to a digital system, in which a continuous sequence of binary numbers, rather than voltages, represent some changing physical quantity.
