A) For each of the sinusoidal source functions, determine the complex exponential source that has the given source as its real part.
a) v(t)=5cos(6t)
b) v(t)=5sin(6t)
c) v(t)=10sin(2t-120 degrees)
d) v(t)=3cos(10t+135 degrees)
B) For each of the sinusoidal source functions, determine the complex exponential source that has the given source as its imaginary part.
C) Determine the phasor representation of each of the sinusoidal source functions.
The DC shunt motor is running at full load with a supply voltage of 440 V and a supply current of 70 A. The rotation speed in full load is 1000 rpm, the field resistance is 200 Ohm and the armature resistance is 0.2 Ohm.
Consider the convolutional code described by connection polynomials
construct a vertical line on your I versus V graph at the point V=5V. this line will intersect each of the sloping lines at two separate points. explain the significance of these intersections.
Sometimes audio (or any) signals x(t) are decomposed into a sum of sinusoids. Consider x(t) the sum of three sinusoids of frequencies 518Hz, 730Hz, and 524Hz whose amplitudes are 1/2 of their corresponding frequencies.
Design a circuit to capture the pressing of buttons (momentary switches). The circuit should have two LEDs "A" and "B", and two buttons, "A" and "B". Whichever button was last pressed should determine which of the two LEDs is lit.
Earth-based 802.11a or 802.11g wireless LAN standards transmit data using a bandwidth of 16.56 MHz. What is the theoretical thermal noise level (in V) in an ideal receiver operating with an input impedance of 50 ohms
Sketch the amplitude spectrum of a DTMF signal with finite duration. You should make this sketch by hand, using the Fourier transform expression obtained in part 1). What happens to the DTMF spectrum when T is "too small"
A square plate of titanium is 12cm along the top, 12cm on the right side, and 5mm thick. A normal tensile force of 15kN is applied to the top side of the plate. A normal tensile force of 20kN is applied to the right side of the plate.
The transfer function of a circuit is given by H(s)=2 s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator. b. What is the characteristic equation o..
An electric heating element is connected to a 110 v circuit and a current of 3.2 A is flowing through the element. How much energy is used up during a period
The total current in a semiconductor is constant and is composed of electron drift current and hole diffusion current. The electron concentration is constant and is equal to 10^17 cm^-3. The hole concentration is given by p(x)
