Convolution in matlab using for loop?
There are a lot of convolution functions in matlab, mostly in the signal processing toolbox, so it depends on what you want to do. Matlab has extensive help files available online.
How do you modulate in matlab without using matlab tools?
You would have to write your own code for a modulation (Matlab has a convolution function not in the tools), otherwise you can use its built in function in the signal processing toolbox.
Diff between linear and circular convolution?
there is a big difference between circular and linear convolution , in linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular patteren ,depending upon the samples of the signal
What are the uses and application of matlab in engineering?
Matlab is matrix laboratory. It concerts every input data into a matrix and performs various operations on it.Matlab is specifically used in signal processing in engineering.Various signal processing operations like convolution, correlation, filtering and transforms involve mathematical operations. These can be easily performed in Matlab.The major applications involvesignal processingimage processingspeech processingaudio processingvideo processing
What is the difference between xilinx and matlab software?
Xilinx is a package. Matlab is a package and language. Xilinx requires a HDL program to execute the required logic. Matlab requires the Matlab program for that purpose. Xilinx is used for digital electronics. Matlab is used for signal processing.

What is the importance of convolution in system characterization?
Convolution is used in DIGITAL SIGNAL PROCESSING to predict the output of the system with only a few limited number of samples of the input signal and a few limited number of samples of the impulse response of the system. i.e. if we can state that if you know the impulse response of a system then you can predict the behavior of the system for any signal provided it as an input. It also helps to show that the system is stable or not i.e. we say that a system is stable if its impulse response is absolutely summable or square summable (both are sufficient conditions but not necessary conditions).

What is convolution of a signal?
the convolution of a signal is to filter the components of the signal. The convolution does not mean the masking. Masking means it is going to remove all the masked components(both high and low frequency components).But convolution is going to remove any one (either low r high frequency) depending upon the filter response.

there is a big difference between circular and linear convolution , in linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular patteren ,depending upon the samples of the signal
A sentence with convolution?
The convolution of the input signal with the filter produced the desired output response.
What is the impulse response of R-L circuit?
The impulse response of an R-L circuit is an exponentially decaying signal. It represents the behavior of the circuit when subjected to a Dirac delta function input or an impulse signal. The response decays over time due to the inductor's energy storage capability.
Applications of Circular convolution?
for finding convolution of periodic signals we use circular convolution
Why you do convolution instead of multiplication?
Convolution is particularly useful in signal analysis. See related link.

Difference between linear and circular convolution?
circular convolution is used for periodic and finite signals while linear convolution is used for aperiodic and infinite signals. In linear convolution we convolved one signal with another signal where as in circular convolution the same convolution is done but in circular pattern ,depending upon the samples of the signal
State the applications of linear convolution?
Convolution and related operations are found in many applications of engineering and mathematics. * In statistics, as noted above, a weighted moving average is a convolution. * In probability theory, the probability distribution of the sum of two independent random variables is the convolution of their individual distributions. * In optics, many kinds of "blur" are described by convolutions. A shadow (e.g. the shadow on the table when you hold your hand between the table and a light source) is the convolution of the shape of the light source that is casting the shadow and the object whose shadow is being cast. An out-of-focus photograph is the convolution of the sharp image with the shape of the iris diaphragm. The photographic term for this is bokeh. * Similarly, in digital image processing, convolutional filtering plays an important role in many important algorithms in edge detection and related processes. * In linear acoustics, an echo is the convolution of the original sound with a function representing the various objects that are reflecting it. * In artificial reverberation (digital signal processing, pro audio), convolution is used to map the impulse response of a real room on a digital audio signal (see previous and next point for additional information). * In electrical engineering and other disciplines, the output (response) of a (stationary, or time- or space-invariant) linear system is the convolution of the input (excitation) with the system's response to an impulse or Dirac delta function. See LTI system theory and digital signal processing. * In time-resolved fluorescence spectroscopy, the excitation signal can be treated as a chain of delta pulses, and the measured fluorescence is a sum of exponential decays from each delta pulse. * In physics, wherever there is a linear system with a "superposition principle", a convolution operation makes an appearance. * This is the fundamental problem term in the Navier Stokes Equations relating to the Clay Institute of Mathematics Millennium Problem and the associated million dollar prize. * In digital signal processing, frequency filtering can be simplified by convolving two functions (data with a filter) in the time domain, which is analogous to multiplying the data with a filter in the frequency domain
