Write the difference equation for a four-term moving average filter.
The input cos(n/3)u[n] is then passed through the four-term moving average filter. Solve for the first 5 samples of the output.
Given a sampling frequency of 8kHz, which input frequency would you be able to eliminate completely with this moving average filter.
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Port B, which is connected to an LED.
A cold heading operation is performed to produce the head on a steel nail. The strength coefficient for this steel is 600 MPa, and the strain hardening exponent is .22. Coefficient of friction at the die-work interface is .14.
A p-n junction solar cell has Voc = .5 V and Jsc = 20 mA/cm2. A second cell of same area has Voc = .6V and Jsc = 16 mA/cm2. Assuming both cells obey ideal diode equation find the values of Voc and Jsc when connected in parallel and series
Suppose you are designing a power amplifier for a loudspeaker which has an equivalent resistance of 150 . What should be the Thevenin equivalent resistance of the power amplifier in order to maximize the power transfer to the loudspeaker
what would the relative sensitivity of the IR detector be if you use FREQOUT to send a 35 kHz harmonic? What is the relative sensitivity with a 36 kHz harmonic?
(d) Use the colon operator to create a matrix D by extracting the first through third columns of matrix A. (e) Create a matrix F by extracting the values in columns 2, 3, and 4 and combining them into a single column matrix. (f) Create a matrix G tha..
A 10 uH inductor is connected to a circuit such that prior to t = 0 the current through the inductor is 10 mA. After t = 0 the current through the inductor is iL(t) = 10e^(-1000t) mA where t is time in seconds. a) Determine the expression for indu..
Consider a three-phase distribution feeder with line reactance of10 ohm supplying a three-phase Y-connected load of 200 kVA at power factor of 0.85 lagging.
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.
Compare the frequency response magnitudes for each of the responses above (will need to plot on a logarithmic scale). Comment on the observations noting things such as if the signals are resolvable, the size of the side lobes, etc.
estimate results in the lights being switched on for an average of 19 hours per day - 6 hours more than needed. The room is lit with seven, 60 W incandescent bulbs, which you can assume are powered by a 115 V constant voltage source.
Consider the 1D system whose input-output equation is given by g(x) = f(x)*f(x), where * denotes convolution. a) Write an integral expression that gives g(x) as a function of f(x). Hint: Convolution definition
