Assume that the cruise control system of an automobile analyzes the speed and the acceleration of the vehicle to operate. To transmit this information to the cruise control unit, an analog computer unit is required.Given an electronic sensor, measuring the speed and outputing it in voltages, we are asked to design this computer unit. Design an analog computer, getting the speed information from a sensor and returning speed + 3 times the acceleration value to the cruise control unit. Realize this task using operational amplifier circuits.
A single-phase circuit is placed across a 120-V rm, 60-Hz source, with an ammeter, a voltmeter, and a wattmeter connected. The instrucments indicate 12 A, 120 V, and 800 W, resppectively. Find (a) the power factor, (b) the phase angle
All numbers are expressed in hex notation. For the following three instructions, each is executed from the above initial state. Assume each instruction is independent of the others: MOVE *R2, R1 move R1 to what R2 is pointing at
Does the carrier frequency of a system have an impact on small scale fading and shadowing. when moving over a distance x,will variations in received signal power be greater for low frequencies or high freq and why.
There are approximately 109 million TVs in the United States. Each uses, on average, 79 W of power and is turned on for 6.9 hours a day. If electrical energy costs 0.073 dollars per kWh, how much money is spent every day in keeping the TVs turned ..
The range of an analog signal is 2 Vpp, and the samples of this signal are being quantized. The quantizer-output word size is 10 bit. What is the quantization interval Q
Determine the conductivity of silicon at T = 300 K if it is doped with donor impurity atoms at a concentration of 1.25*1016 cm-3. Assume that the electron and hole mobilities are 1350 cm2 / V-s and 480 cm2 / V-s, respectively.
Obtain a minimized equation for the function F(X,Y,Z)=Σ(0,1,3) + Σmd(5,6,7) then draw a schematic to implement the minimized function in SOP form using AND, OR and inverters. Draw a schematic implementing the function using only NOR and inverters.
A 10m diameter cylindrical tank is emptied by a constant outflow of 1 m3 /min. A two position controller is used to open and close a fill valve with an open flow of 3 m3 /min. For level control the neutral zone is 1m and the setpoint is 10m.
An incandescent light bulb can be modeled as a resistor with a value of a few ohms. Imagine an incandescent light bulb goes out in your house. Using your trusty multimeter, how would you check if the bulb is bad and needs replacing
A 2-input NOR gate has inputs A and B. If the output of the gate remains LOW independent of the state of input A, what can be deduced about B
An FM receiver has a Foster Seeley discriminator that has a transfer ratio K = 0.03v/khz. If the maximum IF deviation is 75Khz, what is the maximum output voltage of the discriminator What is the minimum output voltage of the discriminator
