You're driving over a bridge at 65.0 km/h, listening to an AM radio station broadcasting at 535 kHz The station's transmitting antenna is directly behind you, and its signals are reaching your car both directly and after reflecting off a metal bridge struc- ture ahead of you. The resulting interference means that you experience a varying signal strength. What's the time you per- ceive between the maximum signal strength and the following minimum signal?
Consider a rock thrown off a bridge of height 79.8 m at an angle theta = 25 degree with respect to the horizontal as shown in Figure P4.20. The initial speed of the rock is 10.5 m/s. Find the following quantities: the maximum height reached by the rock the time it takes the rock to reach its maximum height the time at which the rock lands how far horizontally from the bridge the rock lands the velocity of the rock...
art A Based off Week 2 Content ее An H-bridge is a circuit that can be used to control a motor using simple on/off switches (see figure below S1 S3 S2 S4 Fig. 1. H-bridge Circuit We can describe the state of the switches in this circuit using an array. Within the array, 0 means the switch is off and 1 means the switch is on Example: 1,o,1.0] means switches 1 and 3 are on, while 2 and 4 are...
P1. How does H-bridge circuit help in motor functioning? Explain in detail with a circuit diagram. P2. What are the other applications of H-bridge encoder that you can think of? P3. How will the encoder work when a PWM signal is applied? How does the mode of operation change? Consider PWM signal as a regular square wave signal.
9 T F Any control system must capable of reducing errors to some small value and the system must be stable. 10 T F Delay time is the time needed for the response to reach 0.6 final value at the very first time. 11 T F The settling time in the second order system is 4 times of time constant. 12 T F Using PD controller in the position control system with a ramp input, to reduce the steady state...
6. (20 points) (1) Design an analog lowpass filter with a cut-off frequency of 9 rad/sec by starting with an analogue prototype first-order lowpass filter with cut-off frequency of 1 rad/sec. Show the system transfer function H(s) (2) Design an IIR digital filter Hz) that corresponds to the above H(s) by using the bilinear transform method without prewarping with T 0.1 second. Show the system transfer function Hz) and find its corresponding digital cut-off frequency Be approximately (3) What is...
Pre-Laboratorv Exercise: You are to design a state machine capable of controlling a 4-phase unipolar stepper motor. This motor operates by energizing one (or more) of four coils of wire at a time to rotate a magnetized shaft to predetermined positions. Let us call the four coils A, B, C, and D. To make the motor rotate properly, the coils need to be turned on (driven at logic "1") and off (driven at logic "O") in the following sequence: ABCD-...
Two men are standing on a bridge, getting ready to bungee jump
off using the same bungee at the same time. The masses of the men
are 100 kg and 70kg. The k of the cord is 3 kN/m.
What is the maximum L can be so that at full length, it will
just barely reach the water 100 meters below?
After the men reach the water, the heavier one legs go and stays
in the water, launching the lighter...

QUESTION 6 Зро Design a second-order IIR digital low-pass filter using Butterworth approximation. Use the bilinear transformation to convert the analogue fiter to a digital one (choose the sampling period T- 2 s and the cut-off frequency as 1 rad/'s). Express the digital transfer function of the filter H(z) as: In the box below, provide the numerical answer for b1.
