(1)インパルス応答から位相特性を計算するプログラムを作成せよ。ただし、
が数学的に未定義であることに注意してプログラムを作成しないと、振幅の値がゼロに近づく周波数でプログラムが実行時エラーを起こす場合がある。
(2)インパルス応答から群遅延特性を計算するプログラムを作成せよ。この
結果から、
と
の波形の時間的なずれを定量的に考察せよ
(3)位相特性と群遅延特性は、実質的に同じことを異なる表現で示しているにすぎないことを、実験結果から考察せよ。
(4)http://momiji.i.ishikawa-nct.ac.jpにより、各種のFIRおよびIIRディジタルフィルタが設計可能である。様々なフィルタの設計を行なってみよ。また、得られたフィルタ係数を利用して、ディジタルフィルタを実現せよ。
Questions & Answers
A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?
A mouse of mass 200 g falls 100 m down a vertical mine shaft and lands at the bottom with a speed of 8.0 m/s. During its fall, how much work is done on the mouse by air resistance
Can you compute that for me. Ty

what is the dimension formula of energy?
Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes

please, I'm a physics student and I need help in physics

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

A ball is thrown straight up.it passes a 2.0m high window 7.50 m off the ground on it path up and takes 1.30 s to go past the window.what was the ball initial velocity
2. A sled plus passenger with total mass 50 kg is pulled 20 m across the snow (0.20) at constant velocity by a force directed 25° above the horizontal. Calculate (a) the work of the applied force, (b) the work of friction, and (c) the total work.
you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time

Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

what are the types of wave
Maurice
fine, how about you?

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
Who can show me the full solution in this problem?
