Figure P7.54 shows the frequency response Ae(ejω) of a discrete-time FIR system for which the impulse response is
(a) Show thatAe(ejω) cannot correspond to an FIR filter generated by the Parks-McClellan algorithm with a passband edge frequency of π/3, a stopband edge frequency of 2π/3, and an error-weighting function of unity in the passband and stopband. Clearly explain your reasoning. Hint: The alternation theorem states that the best approximation is unique.
(b) Based on Figure P7.54 and the statement that Ae(ejω) cannot correspond to an optimal filter, what can be concluded about the value of L?
a signal franging from 1khz to 100khz will be put into a davice that will need amplification that will output to speakers. A 12v battery is available as a power source, however the current out of the battery should be kept to a minimum.
Objective is just to simulate the system without controller. At some values of wind speeds, I want to play with the duty cycle values of the converter and read its corresponding output power.
Describe the charge transfer mechanisms in a voltage doubler, and show that the output terminal voltage is twice the peak of the input AC source voltage. How would you reverse the polarity of the output voltage in such a circuit?
A small object with charge Q1=6nC is located at the origin. A second small object with charge Q2=-5nC is located at m. What is the net electric field at location A m due to Q1 and Q2
The conductor, its motion, and is the required length of the conductor? It turns out that in generator design, a conductor of this length is impractical, and we must use N conductors of length 0.1 m. However, by connecting the conductors in series..
A pn junction diode and a Schottky diode have equal cross-sectional areas and have forward-bias currents of 0.5 mA. The reverse-saturation current of the Schottky diode isIS= 5× 10-7A. The difference in forward-bias voltages between the two diodes..
Received power of half-wave dipole antennas, Assume that two antennas are half-wave dipoles and each has a directive gain of 3dB. If the transmitted power is 1W and the two antennas are separated by a distance of 10 km, what is the received power?
Calculate current flow and describe its probable path. Will the breaker likely be tripped? Is there a risk of electrocution? If so what factors contribute to the risk?
Draw all force vectors on charge 2 due to every other charge. Label each vector accordingly with two subscripts. Draw the vectors so that the tail of each vector originates on the charge.
