1) Given the transfer function shown below, convert it into a difference equation. z^2-0.7071z/z^2-1.41z+1
2. The impulse response of a discrete time system is given by h(n) = [ 1 -1 2 ].
To such a system we apply an input of the type x(n) = [ 2 1 2 3 ].
3. A system is described by the transfer function below. H(z) = (z^2+0.64)/(z^2+1.8z+1.28)
Find the location of poles and zeros of the system and write them here. Is this a stable system? Why or why not?
4. The transfer function of a discrete time system is given by H H(z) = z/(z-0.5)
The system has a sampling rate of 100 Hz. Calculate the frequency response of the system at 25 Hz input frequency as a complex number in both rectangular and polar form.
Design a circuit using JK flip-flops that takes in a binary stream B0B1B2B3 and outputs 1 at a time t if the stream recieved thusfar (i.e. BoB1..Bt-1Bt), when read as an unsigned binary number, is divisible by 3.
Write a sequence of instructions to initialize and run the timer to geneate an 800 baud rate clock. what would be the baud rate if the intial value of the timer was set to 9AH
Now assume that the doctor knows that 1 in 100 individuals with symptom G will have the rare disease, and he only orders the test when individuals have symptom G. Given that one of the doctor's patients tests positive.
A three-phase load is Y-connected. The load has a phase voltage of 139 V and a phase current of 49 A. Each phase of the load consumes 5.1 kW of power. (A) Sketch and label the load. Find (b) the line voltage, (c) the line current, and
Cradle to death is a typical lifecycle for any given application. The useful life of a particular application will vary based on advancements in a given discipline. It is critical to continuously seek and identify new ways to adapt technology.
An industrial load consumes 88 kW at a power factor of 0.707 lagging from a 480 Vrms line. The transmission line resistance (Rline) from the power company's transformer to the plant is 0.08 Ohms.
A dc series motor of 230 V, 12 hp, 1200 rpm is connected to a 230 V supply. It draws a current of 40 A, and rotates at 1200 rpm. Ra = 0.25 ohms and Rs = 0.1 ohms. Assume magnetic linearity.
A circular coil of 200 turns of radius a=60mm, total resistance R=2 ohm, and no self inductance is rotated about a vertical diameter with uniform angular velocity =200 rad/s in a horizontal magnetic flux B of 0.25 Tesla.
A unity feedback control systems for a robot submarine has a plant with a third-order transfer function G(s) = K / (s(s + 10)(s +50)) We want the overshoot to be approximately 7.5% for a step input
An engineer needs to detect a binary strings of any length or composition provided that each contains at least one substring of "1101". a) Draw the state diagram of this finite state machine.
Design a class - A transformer-coupled emitter-follower amplifier to deliver 10 W to an 8 Ohm speaker. The ambient temp is 25 C and the maximum junction temp is Tj max = 150 C. assume the thermal resistance value are dev-case = 3.2 C/W
