An integer is said to be prime if it is divisible by only 1 and itself. Write a function called prime() that takes in one integer number, and returns 1 (true) if the number is prime and 0 (false) ot
Suppose you have a 2 kW electric heater rated for 220 volt operation, which you intend to operate at a reduced power dissipation of 1kW. Calculate the proper amount of voltage you would need to achi
explain the dilation, erosion, closing, and opening operations on a binary image B with a structured element S. ( you need to use the symbolic notion for the operators, but need not provide the prec
Design a logic circuit, LOGARITHM that converts an input number X to its logarithm, log(X). Input X is given as an unsigned real number such that, 1.00<=X<=7.75, using fixed-point fromat with
Three positive point charges, each with q = 3 nC, are located at the corners of a triangle in the x-y plane, with one corner at the origin, another at (2 cm, 0, 0), and the third at (0, 2 cm, 0). F
Then find the phase relation between the total voltage and current; is it leading or lagging when the frequency is below resonance and above resonance; what is the nature of the circuit in those two
If the cutoff between "insecure" and "secure" were x amount of time, how long would a secure password have to be. State and justify your assumptions regarding the character set from which the passwo
False positive and false negative rates can be adjusted, and they are often complementary: Lowering one raises the other. List two situations in which false negatives are significantly more serious
A combinational logic circuit has 3 outputs as described below: F1=Minterm(0,3,4) F2= minterm(1,2,7) F3= Maxterm=(0,1,2,4) Implement the circuit using a single decorder with active high outputs and ex
