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?

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=

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 (...)

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**".

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 (...)

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?
