x(t) = cos(100πt) - 5sin(600πt) + 3cos(200πt)
(a) Determine the fundamental frequency of signal x(t)
(b) Determine the Nyquist sampling rate such that no aliasing occurs in the sampled signal.
(c) Assuming the sampling rate is 600 Hz, obtain the discrete time signal x[n] after the sampling.
(d) The sampled signal x[n] obtained above is processed by the ideal D-to-C converters with the sampling rate (600 Hz). Obtain the representation of the continuous signal.
Basics problems of Induction motor, The frequency of the induced rotor currents in the rotor of a 60 Hz induction, machine is 2 Hz. Furthermore, the fields in the air gap turn at -40 rpm with respect to the rotor.

A mummy picks up a calculator and starts adding odd whole numbers together, in order: 1+3+5+... etc. What will be the last number the mummy will add that will make the sum on his calculator greater than 10,000
Design and implement a sequence detector using a finite state machine that detects the sequence 1, 1, 0, 1, 0. Consider previous/oldest bits for the sequence detection. Design the fuction using D-Flip-Flop
A certain battery has terminals labeled a and b. The battery voltage is vab = 12 V. a) To increase the chemical energy stored in the battery by 600J, how much charge must move through the battery
Consider an oxide-to-n-type silicon junction at room temperature. The impurity doping concentration in the silicon is Nd=8 x 1015 cm-3. Calculate the maximum space charge width in the silicon.
Suppose you have a line charge and a point charge in space. A point charge of 16nC is located at Q(2,3,5) in free space, and a unifor line charge of 5nC/m is at the intersection of the planes x=2 and y=4. If the potential at the origin is 100V, fi..
The numbers N, A, and B are usually published so that everyone knows them. Suppose A= 21, B= 5, N= 8, and the initial value (or seed) is X(0)=1. Write down the first six decimal numbers that are generated by this algorithm.
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
