    What is the Cross-Correlation Theorem for Continuous Fourier Transform?

    can you help to find a general formula for the autocorrelation function Hermite polynomials. Thanks a lot!

    1. you mean for arbitrary n,m. 2. what do you mean by z. 3. can you tell me how to evalute eq(15) to get this result: δ_n,m 2^n n! sqr(pi). if I you will know how they get this result for Hn, Hm, so I can also evaluted for my equation with Hn * cos (...) but this is my problem I don't know...

    1. please, can tell me how to find the normalization coeffecient N_n? 2. you said different δ _n,m. I know thet δ _n,m is Kronecker delta function, how it can be changed? Thanks a lot!

    do you mean with different N_n which is represented by eq(16)

    As I said to you: let assume that our function g(t) instead of H(t) So that, g(t)= (-1)^n * e^(t^2) * d^n/dt^n * e^(-t^2)* cos (2 pi fc t) we can say that g(t) can satisfied equations 15 and 17 because of its orthogonality properties. Is that true?

    It is a reference which is : A. D. Poularikas, The Transforms and Applications Hand book CRC Press, Boca Raton, Fla, USA, 2nd edition, 2000.

    according to the text that I have and I couldn't attached it here, the coeffecient C_m,n(t) is the the cross correlation function between nth and mth order pulses at point t.

    let assume that our function g(t) instead of H(t) So that, g(t)= (-1)^n * e^(t^2) * d^n/dt^n * e^(-t^2)* cos (2 pi fc t) 1. we can say that g(t) can satisfied equations 15 and 17 because of its orthogonality properties. Is that true? 2. in equation 18, I didnt understand what...

    for Hn(t)= (-1)^n * e^(t^2) * d^n/dt^n * e^(-t^2)* cos (2 pi fc t) where fc will be chosen such as to still keeping the orthogonality of Hn(t) for different integer values for n. so, Psi_n(t)= N_n * Hn(t) where N_n = \frac{1}{\sqrt{2^n*n!*\sqrt{pi}}} according to the definition as...

    what about \int^{\infty}_{-\infty} Hn(t) Hm(t-d) dt where H(t)= (-1)^n * e^(t^2) * d^n/dt^n * e^(-t^2)* cos (2 pi fc t)
