design a logic program that will track the activity for one turnstile. there will be three inputs PHASEA, B and RESET. there will be no output. the program should be able to track 999 total guests. turnstile the two switches, phase a and b that are mounted so that as a guest passses through the turnstile the two switches will turn on in a seqwuence. the sequence depends on whether the guest is entering or exiting the park. when someone enters the gate PHASEA outputs a signal before switch PHASEB. When someone leaves PHASEB outputs a signal before PHASEA. since the two switches are located close togetherk, there wil always be some overlap in their pulse outputs unless a guest starts through a gate and then backs out. if guest backs out, it wil create a false trigger that should not be counted.
Write a program which accepts the frequency of an electromagnetic wave in megahertz and then displays to the user whether the frequency falls in the FM band, AM band, or neither.\FM radio falls between: 87.7 to 108.0 MHz.
The campus bus uses an embedded system that tracks the number of passengers getting in and those getting out of the bus. Two circuits with laser photodiodes, connected to RB0 (getting in) and RB1 (getting out), are used to track these numbers.
The voltage V across a semi conductor in a computer is given by V= aI+BI^2, where I is the current (in A). If a 24 V battery is conducted across the semi conductor, find the current if a=4 ohms and B= 0.5 ohms/A.
1. Provide 3 ways for creating proto-types of an electronic circuit. 2. Explain briefly, in outline form, and in your own words, the procedure for creating a single-sided, PCB (Printed Circuit Board), using the etching procedure.
Suppose a data array has 30 numbers sorted from low to high already, where no two numbers are equal. We need to search whether any of the two randomly given key numbers, key1 and key2 is in the array. If yes, then find out the position index(es) f..
(b) Find and list all essential prime implicants of the F function. (c) Find the minimal two level NAND gate implementation of the F function. Find the gate input cost. (d) Find the minimal two level NOR gate implementation of the F function. Find th..
a 60-kHz sinusoidal signal is applied to an amplifier with a gain of k=2. the circuit is built with an lm741 opamp with power supplies +-13V. find the largest amplitude the signal may have before it is limited by slew rate constraints.
Determine whether the Boolean funcions F=a'c+ab'c+ab and G=b'c+a'bc+abc+ab are equivalent using algebraic manipulation.
Compare GBN, SR, and TCP(no delayed ACK). Assume that the timeout values for all three protocols are sufficiently long such that 5 consecutive data segments and their corresponding ACKs can be received (if not lost in the channel)
If it takes 1 sec to rotate 45 degrees after starting from rest, how long in seconds would it take to instead rotate 81 degrees after starting from rest under the same constant angular acceleration.
the total amount of electricity that could potentially be generated from wind in the U S has been estimated at 10.8*10^9 Mw-hr annually , if one tenth of this potential is developed, estimate the number of 2 Mw windmills
Students should type up, assemble and emulate the BIN2ASCII program which converts the value entered in R3 from Hexadecimal to ASCII. This should be done by dividing R3 by 10 (decimal) and converting the remainder to ASCII
