In a communication system noise is most likely to affet the signal at?
channel
What happen if the bandwidth of signal greater than channel bandwidth?
distorttion
What is the channel bandwidth for 2KHZ signal?
depends on type of modulation and other variables
What are analog and digital modes of operation of an instrument?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission. In digital communication, the message signal to be transmitted is digital in nature. This means that digital communication involves the transmission information in digital form Example: ASK, FSK, PSK.
Why power amplifier are called as large signal amplifiers?
in general the CE amplifiers are called low-signal amplifiers as they use only small values of voltage as a source of input which cant be used in practical purposes, whereas power amplifiers deal with practical values of input and output voltages
What is the difference between multichannel and multidimensional signals?
if a signal is a function of single independent variable,then signal is called multichannel signal. if a signal is function of multiple independent variable then signal is called multidimensional signal.
What is multichannel and multidimensional signal?
Multichannel Signals. Signals which are generated by multiple sources or multiple sensors are called Multichannel signals. These signals are represented by vector.S(t) = [(S1(t) S2(t) S3 (t)]Above signal represents a 3-channel signal. In electrocardiography, 3-lead and 12-lead electrocardiograph is often used in practice, which results in 3-channel and 12-channel signals, respectively.Multidimensional Signal. A signal is called multidimensional signal if it is a function of M independent variables. For example : Speech signal is a one dimensional signal because amplitude of signal depends upon single independent variable, namely, time. TV Picture Signal : A B/W picture signal is an example of 2-dimensional signal because brightness of the signal at each point is a function of two spatial independent variable, namely, x and y. Variables x and y are width and height of the picture element.A colored picture signal is an example of 3-dimensional signal because brightness of the signal at each point is a function of three independent variables, namely, x, y and time (t).-------Arif, RUET.
Who invented the first practical radio signal system?
the first practical radio signal system is Jan Hendrix Campos
What is the difference between wideband and narrowband?
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
What is the frequency of mono?
There is no frequency of mono. Mono is a one channel signal, stereo is a two channel signal.
1 wireless microphone on two receivers?
Yes, if you tune the microphone to for example channel 2, and both of the receivers to channel 2 also, you will be able to get the signal on both receivers.
What has the author Stephen Edward Dollar written?
Stephen Edward Dollar has written: 'Multidimensional analysis of the electroencephalogram using digital signal processing techniques'
A physical path or a frequency used for signal transmission?
communications channel
Is it right that a television channel is characterized by frequency of transmitted signal?
Yes, this is a true statement. A TV channel is most often characterized by the frequency of its transmitted signal.
Calculate the capacity of a telephone channel of 3000hz and signal to noise ratio of 3162?
Calculate the capacity of a telephone channel of 3000hz and signal to noise ratio of 3162?
What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
Why is your everybody votes channel on your Wii not working?
Because your Nintendo wii can't get the signal of your wifi.AnswerBecause your Nintendo wii can't get the signal of your wifi. But the internet channel works.
