## Discrete time linear convolution

Hi, i am new to dsp. i just learnt that the convolution of the given sequence with the impulse response of the system gives the output sequence. the length of the output sequence is sum of the lengths of the sequences - 1.but in this case the outputs are more than the input.how is this possible?

## Kindly help me for this question of convolution

I am having a question that Given a pair of sequence, use discrete convolution to find the response to the input x of the linear time invariant system with impulse response h x= y= compute the convolution of two finite length sequences what i have to do. simple convolution of x and

## About linear transformations

Hi everyone, as it is known that multipliction of two signals in time domain is equivalent to convolution in frequency domain. moreover for discrete fourier transform or z-transform etc multiplication in time is equivalent to "circular convolution" in frequency. Now for any arbitrary linear transform (say A) with (...)

## Serious doubt regarding Convolution !!!

For finite length discrete-time sequences, the multiplication in the frequency-domain corresponds to circular convolution of the sequences, rather that linear (ordinary) convolution. Look for "circular convolution". Regards Z

## Can linear convolution technique be applied to discrete linear shift variant systems?

Hi, I was wondering whether the linear convolution technique can be applietd to discrete linear shift variant systems?? From what I have understood, if the signal is time /shift varying, then for applying convolution, I might have to use circular convolution as a result of foldback. Anyone (...)

## discrete-time linear convolution

i'm supposed to compute linear convolution x*x. based on the definition, it is infinity sum. so, how should i go about computing this? it seems i should limit to, say 100 values and compute based on those 100 values only?
