Develop and implement the counter that counts the sequence 000, 100, 111, 010, 011 and repeats. Include a reset input that, whenever it is asserted, immediately resets the circuit to 000. Also include an input called "count" which when asserted enables the circuit to transition between states, but when deasserted leaves the circuit in the most recent state entered. Enable the circuit to be sequenced by either manually depressing a pushbutton, or by the square wave waveform generator (operating at approximately 1.0 Hz) on the breadboard station.
Design the counter using D-flip-flops such that the state codes are the output values of the circuit. For example, when the circuit is in state 011, the output LED's display "off" "on" "on". Thus, no output equations need to be designed. Rather, only flip-flop input equations need to be derived for the circuit.
An optical lithographic system has an exposure power of 0.3 mW/cm2. The required exposure energy for a positive photoresist is 140 mJ/cm2 and for a negative photoresist is 9 mJ/cm2. Assuming negligible times for loading and unloading wafers
Write a program to determine how many from your data set called MYDATA, which is a set of unsigned single-byte numbers, are odd numbers. Save the result in TOTODD at address 0x10 in the data memory.
Construct a 4-to-16-line decoder with five 2-to-4-line decoders (74LS139A). Use a block diagram for components and clearly show your address select variables.
(a) What is the tension in the coupling between the first car and the locomotive? (b) If this tension is equal to the maximum force the locomotive can exert on the train, what is the steepest grade up which the locomotive can pull the train at 25 ..
Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
Important information about Electrical Networks, Engine consumes 5kw of power and a reactive power of 2kvar at current of (3+j2) Amps.
A rectangular chip has a top surface of 0.5 cm by 2 cm cooled by air at 20 oC with h = 150 W/m2.K. There are also 16 connector pins, 1 mm wide, 0.5 mm thick, 6 mm long and k = 60 W/m.K attached to a circuit board at 30 oC.
The required exposure energy for a positive photoresist is 140 mJ/cm2 and for a negative photoresist is 9 mJ/cm2. Assuming negligible times for loading and unloading wafers, compare the wafer throughput for positive photoresist and negative photor..
Use computer graphics/ or by hand to illustrate 6-pole stator winding of an AC machine. For wt = 0 and wt = 180o show the phasor diagram of phase currents, polarity of currents in individual conductors, and the flux paths.
Using the symbols we've learned in class (standard symbols used universally), draw a schematic showing the circuit of a 12-V car battery (represented as a voltage source connected to a light bulb (represented as a resistor).
A 1 W power source is connected to the input of a directional coupler with C=20 dB, D=35 dB, and an insertion loss of 0.5 dB. Find the output powers (in dBm) at the through, coupled, and isolated ports. Assume all ports to be matched.
