A radio channel has a bandwidth of 10 KHz and a SNR of 15 dB. What is the maximum data rate that can be transmitted:
(a) Using any system?(b) Using a code with 64 possible states?
For the function G(x) = x + 32 / x^2 A) Determine the relative minimum of G B) Describe the concavity for all values of x except zero
The space between the plates of a parallel-plate capacitor is filled with a dielectric whose permittivity varies linearly from f1 at one plate (located at y=0) to f2 at the other plate (located at y=d).
Determine the peak-to-peak current ripple in the output inductor for a forward converter and determine the output voltage ripple of the converter . We know the following parameters: duty cycle d, input voltage Vin, turn ratio: N1/N2
A first-order allpass filter impulse response is given by h(t) = - d(t) + 2e^(-t)*u(t) a) find the zero-state response of this filter for the input e^(t)*u(-t). b) sketch the input and the corresponding zero-state response.
Consider a unity feedback system with open loop transfer function G(s) (a) sketch the root locus of the system as k changes from zero to infinity. (b) if a series compensator with a transfer function (s+2) is inserted in the above loop, sketch the ..
1) Which has greater efficiency DC Machine operating as MOTOR or GENERATOR 2) What happens when an AC supply is given to a DC Machine
Design a power supply using a 24V, center-tapped transformer to supply 12V at 500mA, -12V at 100mA and 5V at 250mA. What is the minimum current rating of the transformer
Suppose a constant force of kinetic friction acts between the block and the surface, with k = 0.53. If the speed of the block at the moment it collides with the spring is vA = 1.4 m/s, what is the maximum compression xC in the spring
The transfer function of a discrete time system is given by H H(z) = z/(z-0.5) The system has a sampling rate of 100 Hz. Calculate the frequency response of the system at 25 Hz input frequency as a complex number in both rectangular and polar f..
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
An AB latch operates as follows: If A = 0 and B = 0, the latch state is Q = 0; if either A = 1 or B = 1 (but not both), the latch output does not change; and when both A = 1 and B = 1, the latch state is Q = 1. Construct the state table and derive ..
