Develop a functional design for a system that measures and displays the speed of a bicycle. Be sure to clearly identify the design levels, function requirements, and theory of operation for each level.The system must:• Measure instantaneous velocities between zero and 75 miles per hour with an accuracy of 1 % of full scale.• Display the velocity digitally and include one digit beyond the decimal point.• Operate with bicycle tires that have 19-, 24-, 26-, and 27-inch diameters.
Design a counter that will execute the numerical sequence 0, 2, 4, 6,repetitively. Unwanted states should be directed into wanted states that give the simplest logic functions. - Identify the number of required JK D-FLIP FLOP;
If a transformer has a turns ratio of 1:5 and a primary voltage of 20 V AC, what will the secondary voltage be?
A certain load takes 10kW at 0.5pf lagging when connected to a 230V, 60Hz source. The supply company charges a penalty when the power factor fall below 0.8. What size of capacitor must be used in order to avoid penalty
Silicon at T = 300 K is doped with arsenic atoms such that the concentration of electrons is n0 = 7 x 1015 cm -3. (a) Find Ec - EF. (b) Determine EF - Ev. (c) Calculate p0. (d) Which carrier is the minority carrier
A delta connected load consists of three identical impedances Z=45 at 60 degrees per phase. It is connected to a three phase, 208-V source by a three phase feeder with conductor impedance Zfeeder=(1.2+j1.6) Ohms per phase.
A certain magnetic core has a core loss of 8.4 W, of which one-third is eddy current loss, when the magnetizing field is changed 60 times a second. determine the core loss if the magnetizing field is changed only 50 times a second.
Consider a cylindrical cavity of diameter D=100 mm and depth L=50 mm whose sidewall and bottom are diffuse and gray with an emissivity of .6 and are at a uniform temperature of 1500 K. The top of the cavity is open and exposed to surrounding that ..
Radio Systems, In design of radio systems that incorporate wireless networks, considerations must be taken such as user access, transmission direction, switching and signal strength.
Calculate Vout (f0), Vout (3f0), Vout(5f0), and Vout(7f0) of the frequency spectrum of a triangle wave (A = 10 V and T = 1 ms) passed through a low-pass R-C filter (R = 10 k-ohm and C =5 nF).
Design the minimum-cost circuit and compare its cost with combined costs of two circuits that implement f and g separately. Assume that the input variables are available in both uncomplemented and complemented forms.
A 340 V, 6 pole dc Shunt motor has the following parameters: Rating: 35 kW Current: 122 A Speed: 1000 rpmArmature resistance: 0.35 Ohm Sunt field resistance: 150 Ohm Friction&Windage loss: 1.2 kW
