Design a second-order band-pass IIR filter with center frequency of 450 Hz when the sampling frequency is 2,000 Hz. In order to ensure the filter stability, set the poles at 0.96 radial distant from the origin, and to eliminate the filter output delay, place two zeros at the origin.
Dispense requested amount using least number of bills, Write a C program for an automatic teller machine that dispenses money. The user should enter the amount desired (a multiple of 10 dollars)
(a) How many atoms are there in the unit cell characterizing the Si lattice (b) Verify that there are 4.994 X 1022 atoms/cm' in the Si lattice at room temperature. (c) Determine the eenter-to-center distance between nearest neighbors in the Si lattic..
A jet has 4 engines. Each engine gives a FAIL signal which is TRUE if the engine is broken, and is FALSE if the engine is working fine. The plane can fly as long as at most 1 engine is broken.
A recording trace r(t) is definedas r(t) = s(t) + n(t), where s(t) =10sin(20?t) (i.e., a 10 Hz sine wave, given f= 2f) is the signal and n(t) = sin(120t) (i.e., the 60 Hz electromagnetic noise) the noise.
Explain briefly from what you notice about the digital output values in (a) why a digital output value of an A/D converter is rarely the exact same digital value as the analogue input value.
A 300 V, 60 A, 1200 rpm series dc motor has an armature and series field resistance of .2 ohms each. When a .10 ohm resistance is connected in parallel to the winding, the motor's torque is doubled.
y[n]=x[n]+0.8x[n-5000]+0.6x[n-8000] a) Find the delay in seconds for each echo if the sampling rate is Fs=10000 Samp/sec. Td1 and Td2 a) Find the unit sample response for the filter written as the sum of delayed unit-samples.
You are lowering two boxes, one on top of the other, down the ramp shown in the figure by pulling on a rope parallel to the surface of the ramp. Both boxes move together at a constant speed of 16cm/s.
In the differential amplifier shown in the schematic, R1 = R2 = 10 k ohm; R3 = R4 = 100 k ohm. Assume the ECG voltage at V1 = 100 mV, and the ECG voltage at V2 = - 100 mV. There is a power line interference of 200 mV at both input sites.
A digital signaling system is required to operate at 9600 bps. If a signaling element encodes a 8-bit word, what is the minimum required bandwidth of the channel?
Plot the signal x(n) 0
The lifetime of a turtle is a continuous value uniformly distributed between 50 and 150 years. Let X and Y be the lifetimes of two randomly chosen turtles, and consider the following events: A = {X
