1.) Three separate tones must be extracted from a noisy signal. The frequencies of the tones are 100 Hz, 300 Hz, and 450 Hz. The sampling rate is 1 kHz. Describe a low pass, a band pass, and a high pass filter that could be used to detect the individual tones. The cut-off frequency (or frequencies) for each filter should be 50 Hz from the tone it must detect. Identify the filter types, the cut-off frequencies, and the bandwidths.
2.) The impulse response of a filter is given by h[n]=delta[n-1]-0.28[n-2].
The input to the filter is x[n]=u[n]-u[n-7].
a.) Find the output.
b.) In (a), identify those output samples influenced by boundary effects.
3.) If the bandwidth of a low pass filter is 2 kHz, what is its cut-off frequency?
Store the arrival times in memory locations starting from $1000.(Do this is in C. Store the results in an array and don't worry about the speci c location of the results.)
Eble Company proposes to invest $6 million in a new type of text printing equipment. The fixed costs are $1 million per year. The equipment is expected to last for 5 years. The manufacturing costs per hammer is $1. Calculate the break-even volume ..
(b) If the molecular weight of bombykol is 238.4 amu, what is the molecular formula (c) If 5.698 g of bombykol is burned in excess oxygen to form 16.83 g of CO2 and 6.452 g of H2O, how many grams of carbon were present in the original sample
The voltage on bus 1 is 1.0 per unit (pu) at 30 degrees; the voltage on bus 2 is 0.95 per unit at 5 degrees. The reactance connecting bus 1 to bus 2 is 0.5 per unit Ohms, and the resistance is negligible. a)How much real power (pu) is flowing from ..
A tooling designer is designing a jig that will insert pins into the flip-up handles of a coffeemaker. The bin to hold the pins should hold enough pins for 3 hours' work before reloading. The engineering estimate for the rate of inserting the pins..
1. Sketch the polar plot of the frequency response for the following loop transfer functions: Gc(s)G(s) = 1 / ((1 + 0.25s)(1 + 3s)) Gc(s)G(s) = 5(s^2 + 1.4s + 1) / (s - 1)^2 Gc(s)G(s) = (s - 8) / (s^2 + 6s + 8) Gc(s)G(s) = 20(s + 8) / (s(s +2)(s + 2)..
What should the signal definitions be for the equations, such that the minimal about of hardware (gates) are used assuming we have an abundance of NAND gates Show the signals definitions and resulting circuitry.
A block error detecting code has a minimum distance of three. How many errors can this code detect and how many can it correct
Single Phase Circuit, A resistor and a capacitor are connected in series across a 150 V a.c supply. When the frequency is 40 Hz the current is 5 A
A three 120 - V power line is Y-connected. The three phase outputs are marked as a,b,c. The neutral is marked as n. The phase sequence is abc. It is connected to a balanced Y- connected load, with the impedance is 12 + j 9 omega.
Write C code that senses 3 accelerometer readings into pins PAD 8, 9 and 10 and displays them on the LCD. Also run a timer in seconds and log the values of the accelerometers in 3 arrays every second.
The line is terminated in a load RL = 25 ohm. Use the bounce diagram to plot V(t) at a point midway along the length of the line from t = 0 to t = 25 ns.
