unit impulse function δ is 1 when n=0 and 0 to n !=0. its called Kronecker delta ( ) for FIR filters generally y = x * h; when you take δ as an input (x=δ) u got y = δ*h. then δ = 1 when n=0 and 0 when n /=0 so y=h
I wish to design a digital carrier generator, the diagram of which i am attaching herein..for the same i have used the following building blocks: 1> 2:1 Mux(multibit) 2> Digital Integrator (multibit) 3> A Delta function block (unit impulse function) 4> A Clock 5> A 4x4 bit multiplier, wherein only the first 4 bits of (...)
Basic operations on matrices 2. Generation of various signals and sequences( periodic and aperiodic) such as unit impulse, unit step, square, saw tooth, triangular, sinusoidal, ramp, sinc function 3. Operations on signals and sequences such as addition, multiplication, scaling, shifting, folding, computation of energy and (...)
Hi, I now it is a novice question but I am confused. In Rabiner's Speech Proc. STFT is defined as: X_n(e^{j\omega})=\sum_{m=-\infty}^{\infty } w(n-m)x(m)e^{-j\omega m} Suppose our signal is all 1s, and window function is unit impulse (just for simplicity). So that in every window we again have unit (...)
I have an elementary question in Signal Analysis. The unit impulse function has this property x(t).δ(t) = x(0).δ(t) ---------(1) ∫x(t).δ(t)dt = x(0) ----------(2) How are these two expression different? I think eq (1) should be equal to x(0). Please clarify me on this. Regards M
Hello, I came across a statement (un-proofen) that the limit (K--> infinity) of 1/(T*K)*sin(f*pi*K*T)/sin(f*pi*T) is given as 1/T?*∑u(f-n/T) where u is the unit impulse function. Does anyone know how to arrive at this value? Cheers,
