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 (...)

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,
