2. Borgmann adopts a number of Heidegger’s criticisms about technology. But unlike Heidegger, Borgmann disagrees that we should try to go back to a pre-technological attitude to mitigate against the negative aspects of technology. He embraces technology as a part of the experience of focal things and practices. Explain the role technology plays in Borgmann that is different from Heidegger using an example.

In this part of the assignment, you will need to calculate the cross-correlation of two random signals. In the Appendix: Part II, we include the function ccorr that gives you the crosscorrelation of two input vectors.

MATLAB provides other built-in function that may be useful for this part of the assignment

• max: gives you the maximum value of a vector. For more information type help max

find: gives you the index corresponding to a value of a vector. For more information type help find.

Finally, you will also need to use a linear filter in Exercise 3. You can use the function linfilt that you already used in MA2.

You can calculate the cross-correlation between two random signals in MATLAB by using the function ccorr given in the Appendix: Part II. As an example, consider two random signals x(t) and y(t), which are both modeled as white Gaussian random processes with mean 0 and variance 1. We plot the cross-correlation function Rxy(? ) of the random signals x(t), y(t) by applying the following MATLAB code:

t = -10:0.01:9.99;

x = randn(1, length(t));

y = randn(1, length(t));

[cc, tau] = ccorr(x,y,t);

plot(tau,cc);

In the same way you can plot the autocorrelation of signal x(t) [ac, tau] = ccorr(x,x,t); plot(tau, ac);

Now assume that y(t) is the output of a linear filter with impulse response h(t) = |sinc(t ? 2)|

where the input x(t) is a white Gaussian random signal with mean 0 and variance 1. Create an M-file to:

(a) Calculate y(t) using the function linfilt and plot x(t) and y(t) where t ranges from ?10 to 9.99, using 0.01 increments. NOTE: y(t) is the output signal of the filter, so if N is the length of the vector t, the length of y(t) is N + N ? 1 (convolution of two functions with length N). You will have to find the indices that correspond to t from ?10 to 9.99.

(b) Plot the cross-correlation function Rxy(? ).

(c) Plot the autocorrelations Rxx(? ) and Ryy(? ) of x(t) and y(t), respectively.
