Garage Door Controller Solve exercise 9.7 using SystemVerilog instead of VHDL.
Exercise 7 in Chapter 9
Garage Door Controller This exercise concerns the garage door controller seen in section 5.4.5, designed with VHDL and SystemVerilog in sections 6.7 and 7.6, respectively. Make the modifications needed in the VHDL code to incorporate the following feature: the door must close automatically 30 s after arriving at the completely open position. This feature should be optional, so an input must be added to the circuit to allow the user to choose between enabling it or not. How many DFFs will be needed to build the entire circuit now?
An hemisphere shell of radius R has a uniform surface charge density σ. The shell spins about its axis at angular frequency ω. Calculate the charge dq lying on the circular strip θ--> θ + dθ at radius R and colatitude θ.
Draw a circuit that shifts cyclically a register to left or toright ans is also able to preserve this register's state. Given aretwo controls C1 and C2 that select any of these three operations.use only NOT, AND and OR gates and D type flip flop.
Assuming isothermal surface conditions, determine the allowable electrical power dissipation per board for the cooling arrangements:
An altimeter can measure 0-100m; using a signal conditioner, this high position is distributed over a voltage range of 0-5V. If an ADC covering the same voltage range outputs 1000 0000, what is the distance measured
An ac bridge has the following constants : arm AB, R= 1,000Ω in parallel with C=0.159μF; BC, R=1,000Ω; CD, R=500Ω; DA, C=0.636μF in series with an unknown resistance.Find the frequency for which this bridge is in balance and determine the value
Explain the process of processor development
Design a series resonant circuit to have a bandwidth of 400 Hz using a coil with a Ql of 20 and a resistance of 2-ohm. Find the values of L and C and the cutoff frequencies
Design a current divider that provides a 1:2 current split. Observe the current and power limitations as in the previous item. Another design constraint is that inserting current meters to measure the current division ratio must not upset this rat..
Prove that the ratio of depth to width of the strongest beam that can be cut from a circular log of wood having diameter d is 1.414
a.) Plot x[n] as a function of n and use the definition of the z - transform to find x[z]. b.) Use the z - transform of u[n] and properties of the z - transform to find x[z]. Verify that the expressions obtained above for x[z] are identical.
a 741C is an op amp with Av= 100000 and a minimum CMRRdB= 70dB. what is the common- mode voltage gain. if a desired and common- model signal each has a value of 5 uV. what is the output voltage.
