    Using fourier and laplace transform to solve PDE

    PDE is type of heat equation. Where have above reference notes? Many book only gives an example of solving heat equation using fourier transform. An exercise asks me to solve it for using fourier and laplace transform: In the heat equation, we'd take the fourier transform with respect to x...

    Fourier transform convolution Question! Please

    O....I have some idea now But I want to start at F {f(t)g(t)} = ∫[1/2pi ∫F(ω)e^iωt dω 1/2pi ∫G(ω)e^iωt dω ] e^-iωt dt How to express to 1/2pi ∫ [1/2pi∫F(ζ)G(ω-ζ)dζ]e^jωtdω >__<

    Fourier transform convolution Question! Please

    Given F[f(t)*g(t)] = F(ω)G(ω) , where * = convolution F(f(t)) = F(ω) ; F(g(t)) =G(ω) How to prove F[f(t)g(t)] = 1/2pi [ F(w)*G(w)] I have to do - F^-1(F(ω)) = 1/2pi ∫F(ω)e^iωt dω = f(t) F^-1(G(ω)) = 1/2pi ∫G(ω)e^iωt dω = g(t) F[f(t)g(t)] = F[F^-1(F(ω))F^-1(G(ω))] =...

    How can I use n- enhancement MOSFET as a switch??? (THANKS)

    Please look at the circuit How can I use HIGH/ LOW to control the MOSFET to ON/OFF?? i.e 1)If Gate >5V.........the path between drain and source = close circuit the load is come to vdd 2)If Gate =0V.........the path between drain and source = open circuit Thanks

    what is the Boolean Equation of 2bit full adder???

    O...sorry How about 2- bit full adder?? I can nit find in the powerpoint attached file Because I found that the S0 S1 and carry is very complex I found S0 is similar to 1 bit full adder....I also is A0 XOR B0 XOR Cin but S1 is very complex Any one can help....thank
