Circuit is needed to divide a 10Hz signal down to 1 Hz. Design two circuits as in the accompanying description. Hook the clock input to a 10Hz clock on the logic designer, and hook the output clock to an LED. Produce logic design for both designs:A) Using only a 7493 4-bit counter. Note asymmetric output on the LEDB) Using a 7493 4-bit counter and 7476 JK flip flop to provide a symmetric square-wave output. And why can't the single flip-flop in the 7493 be used as the divide-by-2 counter?
There is a 50 Mhz clock signal on the FPGA board. we want to have a 1 Hz signal for testing all the designs. Find out what size of the counter we need in order to obtain this signal from the on board clock.
What are the major classes of UML diagrams or drawings. Five a one or two sentence description of the purpose of each type of drawing. What are the major elements that should be included in a dynamic model.
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.
the Electric field intensity of a plane electromagnetic wave is given as E(z) = 8 cos (106 π t ) ix at point ( x=0 , y=0 , z=0 ) . the magnetic field intensity is the positive y direction and the wave propagates in a material with properties ε= ε0..
A small circular parabolic reflector, often referred to as dish, is now being advertised as a TV antenna for direct broadcast. Assuming the diameter of the antenna is 1 meter, the frequency of operation is 3 GHz, and its aperture efficiency is 68%
The can's initial volume at 5 °C is 7.2 × 10-4 m3. The coefficient of volume expansion for aluminum is 69 × 10-6 (C°)-1. When the can and the liquid are heated to 87 °C, 7.0 × 10-6 m3 of liquid spills over.
A knight is riding across a 12.0 m uniform drawbridge as shown in the figure. The right end of the bridge is held up by a cable and the left end is supported by a hinge. The mass of the rider and horse is 355 kg and the mass of the bridge is 493 k..
A 240/40 volt transformer supplies two different secondary loads. One load (a) draws a current of 12 amperes at a lagging power factor of 0.94. The other load (b) draws a current of 12 amperes at a leading power factor of 0.94.
An analog system has a bandwidth of 10 MHz, a photodetector of = 0.5 A/W and ID = 1 nA, and a signal to noise ratio (SNR) of 30 dB. The receiver's temperature is 270 C and the load resistance is 50 .
Design a dc power supply that provides a nominal dc voltage of 12V that will supply a load current of up to 30mA. Use a Bridge rectifier in your design and isolate your circuit by use of a transformer at the input.
Show the truth table for the following circuits: a. A 3 input NAND GATE (Inputs are A,B, and C and the output is Q) b. A 3 input odd parity circuit. (Inputs are A,B, and C and the output is Q) c. A two bit adder with inputs (A1,A0 and B1,B0) and outp..
A gaseous mixture containing 50 mol% hydrogen and 50 mol% acetaldehyde (C2H4O) is initially contained in a rigid container at a total pressure of 760 mmHg absolute. The formation of ethanol occurs according to C2H4O + H2 C2H6O.
