In the TTL circuit in Figure, the transistor parameters are βF = 20 and βR = 0.10 (for each input emitter).
(a) Calculate the maximum fanout for vX = vY = 5 V.
(b) Calculate the maximum fanout for vX = vY = 0.1 V. (Assume vO is allowed to decrease by 0.10 V from the no-load condition.)
An FCT three-state buffer drives ten FCT inputs and a 4.7kΩ pull-up resistor to 5V. When the output changes from LOW to Hi-Z, estimate how long it takes for the FCT inputs to see the output as HIGH.
Design the combinational 3 bit gray to binary code converter for conversion angular position of a shaft into binary code. 1) Complete the truth table 2)obtain the minimal solution with a K map 3) draw the circuit diagram, labels the inputs and output..
figure out how to plot the response of a system given an input. transfer function for the system is: H(s) = 1000/(s^2 + 110s + 1000) input is periodic, and represented by: u(t) - u(t-pi/2)
A three phase transformer is constructed from three 3kVA transformer. Secondaries are wired in Delta configuration with a balanced load. What is the maximun combined power that can be delivered to the load
Suppose the information portion of a packet contains 10 bytes consisting of the 8- bit unsigned binary ASCII representation of string "Link Layer".
Assume that a stuck-at-1 fault occurs at the output of the circuit ((A+B)(B+C))'. Determine the test pattern that detects the fault. Repeat for a stuck-at-0 fault at the output.
Computer security is not an issue for organizations alone. Anyone whose personal computer is connected to a network or the Internet faces a potential risk of attack. Identify all the potential security threats on a personal computer.
What would you consider to be evidence of tit-for-tat pricing? How can you distinguish tit-for-tat pricing designed to sustain "collusive" pricing from competitive pricing?
Calculate the total power dissipated in the op-amp circuit. What are the currents supplied by V + and V -?
explain why the circuit does not operate as a rectifier.
The output is 1 when the pattern abca has occurred an even number of times in x(0,t). Give a state description of the system. Use a state vector approach and a minimum-number-of-states approach.
An AM signal has a carrier frequency of 3 MHz and an amplitude of 5 V peak. It is modulated by a sine wave with a frequency of 500 Hz and a peak voltage of 2 V. Write the equation for this signal and calculate the modulation index.
