Write a function mydft that performs the discrete fourier transform for a signal y(t) sampled at regular time intervals. the function shall take as input the vector of instances in time measurements were taken t and the vector of measured values y. as output the function shall provide the variable a0 representing a0 and the vectors a and b containing ak and bk from the discrete fourier transform (a does not include a0 which is returned in a separate variable).

"it security policy enforcement and monitoring" respond to the following: describe how monitoring worker activities can increase the security within organizations. describe the rationale that managers should use to determine the degree of monitoring that the organization should conduct. explain the extent to which you believe an organization has the right to monitor user actions and traffic. determine the actions organizations can take to mitigate the potential issues associated with monitoring user actions and traffic.

Asequential circuit contains a register of four flip-flops. initially a binary number n (0000 ≤ n ≤ 1100) is stored in the flip-flops. after a single clock pulse is applied to the circuit, the register should contain n + 0011. in other words, the function of the sequential circuit is to add 3 to the contents of a 4-bit register. design and implement this circuit using j-k flip-flops.
