Question 3: (a) (4 points) Recall that the trace of a square matrix is the sum of all its entries from the main diagonal. Show that the trace is linear, in the sense that, trace(aX + βΥ) trace(X) + β trace(Y). Let V be the space of all m × n matrices. A function <..) : V × V → R is defined as (A, B) trace(ABT), A, B E V. (a) (4 points) Using the properties of the trace,...
I got help with task 1 and 2 . can you help me with task 3 and 4
of this question. please help me step for step thanks.
A signal x[n] modulated by multiplying it by a carrier wave cos(2*p1"/cm) to form the signal z[n] = cos(2"p1"Vcm)x[n] ·The modulated signal z[n] multiplies with the same carrier wave to give the signal y[n]=cos(2*pi"Vcm)z[n] and filters with an LT-system to give x-hat [n] . all this are described by the picture below...

Find all (infinitely many) solutions of the system of congruence's: Use Fermata little theorem to find 8^223 mod 11. (You are not allowed to use modular exponentiation.) Show that if p f a, then a^y-2 is an inverse of a modulo p. Use this observation to compute an inverse 2 modulo 7.

I want a comprehensive answer to all of them but could not post
them one by one since they build upon each other.
A research paper by Magnani et al published in Applied Optics in year 2012 mentions a novel technique [1] to achieve a task called 'fringe detection Usually, fringes are detected by comparing the first-difference of input interferometry signal with a threshold. As each fringe usually contains a marked discontinuity, so, in the absence of noise, the first...
