Explain Inverse Discrete-Time Fourier Transform
1. Observe the same things among this formula and the inverse analogue Fourier transform:
2. The range of integration is just now -π to π rather than -∞ to ∞. (π corresponds to half the sampling frequency).
3. Negative frequencies are once again included.
4. With the DTFT, the forward transform is a summation and the inverse transform is an integral. This is because {h[n]} is a sequence whereas H(ej?) is a function of the continuous variable ?.
Singular Value Decomposition (i) initialize a 2x2 matrix m=[4 0.5;0.5 7] Factorize the matrix with SVD [u d v]=svd(m) How the matrix u and v differ? Why is that?
#What are the types of Negative Feedback Amplifier?
Q. What is power gain? Power gain is the ratio of power delivered to the load to power delivered to the amplifier is the power gain. A p =P o /P i =V o I o /V i I s
Q. What is Traffic Intensity? Traffic Intensity: Traffic load on a given network may be on local switching unit, interoffice trunk lines or other common subsystem. For analyti
The dielectric constant of air is practically taken as (A) more than unity. (B) Unity. (C) less than unity. (D) Zero.
Q. Explain the action of a pn-junction with bias. Consider both the forward bias and the reverse bias, and use sketches wherever possible.
sketching of wire 1 is charged and wire 2 uncharged
#question what are the types of lines used there and their application ..
Q. For the circuit shown in Figure, find the phasor values (with peak magnitudes) of ¯I, ¯V R , ¯V L , and ¯V C by using PSpice.
Q. Explain working of Inverting Amplifier? One common op-amp circuit is shown in Figure. For the case of finite voltage gain Ao of an op amp that is otherwise ideal, the output
