perl input argument
Is there a way to have spaces in ARGV[0], ARGV[1] etc in Perl ?
eg if I type perl -w search.pl a1 a2, then the arguments are seperated by space, I have an argument which has a space, How do I deal with it?
Still waiting for an answer ...
Thanks in advance
perl passing single input argument
I have written a small code in Perl to search for a given string in text files in a given directory. I take the directory name and string as input arguments to the perl program. Perl takes the space as the seperator for the argument, this does not allow for...
Re: EIGEN VALUES (significance in LSI systems)
The eigen value of a matrix is defined as follows : if Ax = λx then λ is called the eigen value of the matrix A.
In continuous time signals: e^*(j*Wo*t) is an eigen value for a LSI system H,
since
H(x) = λ*x ---- where x = e^(j*Wo*t)
i.e If the...
Consider this
sin (Wo) = (exp (j*Wo) - exp (-iWo))/2
cosine (Wo) = (exp (j*Wo)+- exp (-iWo))/2
By using fourier series/transformation we know complex signals (including real signals) can be represented in terms of summation/integration of compex exponentials.
So we can see that though a...
I agree with cladiocamera δ[3n-2] doesnot exist.
A simple technique would be to substitute 3n-2 = k
Now δ[k] = 1 for k=0
= 0 for all other k ε I { ...,-2,-1,0,1,2,3 .... }
Thus at k =0 we have 3n-2 =0 which gives n =2/3
δ[3n-2] = 1 at n = 2/3
For any...
Hi ,
δ[n] is discrete time domain signal defined as follows :
δ[n] = 1 n = 0
δ[n] = 0 for all n ≠ 0
δ(t) is ct signal defined as follows :
∫ ( δ(t) , -∞ , ∞ ) = 1 ;
The amplitude of δ(t) is not defined. The area under the curve is 1.
δ(t) (unit impulse ) is a signal with ∞ amplitude at...
I need to know about LMS algorithm ( in the context of equalisers ) .
How is Decision feedback used in equalizers ?
How is adaptive equalisation done?
How can we simulate/ implement such equalisers ?
Any help would be appreciated?
Hi ,
i think i need to frame my question properly , i wish to align characters and not numbers.
for eg given strings Jane Joe Mary etc i wish to store these strings as strings of 10 characters ,the trailing characters being spaces. is there a standard perl function for doing this.
Hope this helps ia m saying the same things that the others said but in a slightly different manner
Fourier representation of a signal is basically unique resolution of the signal into its components
In physics when dealing with vectors , u might have learnt resolution of vector into...
C uses "%6.2f" etc to align numbers properly ? Can it be done with characters in PERL i.e adjusting a group of characters within a field so as to have proper alignment for eg I wish to adjust and align an array of characters into a field of say 10.
sin (n) cannot b periodic for n ==> integer
By definition we need 2 have sin(n)=sin(n+N) for periodicity where N is an integer.
Now sin(n+K*pi)=sin(n) where K is an integer.
therefore N must equal K*pi for sine function 2 be periodic,
K*pi can never be an...
