What is the smallest frequency that can be used to sample each of the following continuous-time signals such that the signal can be recovered from the discrete samples?
(a) \(x(t)=1+cos(2000\pi t)+cos(4000\pi t)\)
(b) \(x(t)=sin(4000\pi t)/\pi t\)
(c) \(x(t)=((sin(4000\pi t)/(\pi t))*cos(2000\pi t)\)
(a) What is the condition for matrix A to have inverse Discuss this in terms of rank, determinant, linear dependence of rows and columns of matrix A, singular or non-singular. (b) Show that if A has inverse then AT also has inverse
There are two printers and two I/O ports available in a system. Process A is using an I/O port and is waiting for a printer. Process B is using a printer. Process C is using a printer and is waiting for an I/O port.
In the movement of a robot arm, the arm is commanded to go from position 1 to position 5. Discuss the rise time, the overshoot, the settling time, and the steady-state error as it applies to the movement of a robot arm
Assume all the capacitors in the circuit below were discharged prior to assembly. The capacitors, resistors, and voltage sources are then arranged as shown in the circuit below. The circuit is then allowed to stabilize.
Draw a state diagram for an FSM (Moore machine) with no inputs and three outputs x, y, and z, where xyz should always exhibit the following sequence: 000, 001, 010, 100, repeat. Make 000 as the initial state.
