MATLAB’s conv() function produces an output that is longer than both the original impulse response and input signals. We will look more at this in the discrete-time signals and systems unit, but think about why this might be happening and how to deal with this when plotting your resultant output.

n= -25:25
x= cos(2*pi*n/.3).*(n>=0)
h= (sin(pi*n/3)/sqrt(3)).*(n>=0)
y= conv(h,x)
n1 = -25:length(y)-1-25 %length is change to n1 (remove this n1 and plot you will see error

1. a) Compute the impulse response of the following filters. If the impulse response is infinite, feel free to stop once a pattern becomes apparent. i. y[n] = 2/3 · x[n − 1] − 1/3 x[n − 2] ii. y[n] = x[n − 1] − x[n − 2] − 1/3 y[n − 2] b) What are the feed-back (b[k]) and feed-forward (a[k]) coefficients of the following filters? You may assume that a starts at delay of k = 1 (i.e.,...
Percent Overshoot Problem for a Unit Impulse Response
The unit impulse of a system (which isn't necessarily 2nd order) is shown in the figure. In the figure, A denotes the shaded area. You must show that the percentovershoot of the output in response to a step input (%OS) is a linear function of the shaded area A. Show also that the %OS is dependent only on A and the transferfunction DC gain.

A company that produces cell phones claims its standard phone battery lasts longer on average than other batteries in the market. To support this claim, the company publishes an ad reporting the results of a recent experiment showing that under normal usage,their batteries last at least 35 hours. To investigate this claim, a consumer advocacy group asked the company for the raw data. The company sends the group the following results: 35, 34, 32, 31, 34, 34, 32, 33, 35,...

A firm produces 400 units of output per week and this firms faced with both input and output competitive markets. This produces a revenue of $20,000 per week. The firm could use capital technology (K1) to produce output together with labor in which case each worker would need 2hours to produce 1 unit of output per unit of K1. The firm could use capital technology (K2) in which case the worker would be able to produce 1 unit of output...

Why does it not make sense for a function to have more than one output for the same input? Provide examples. First , define inputs and outputs ( independent and dependent variables) . Then, define ordered pairs and relations and give examples. Finally, define a function and talk about what particular type of relation is a function. Can you find a real world relation that is not a function? For example: The age of a person is the input and...
