(TCO 1) A signal given by 15 Cos (20t) 20 Sin (40t) is sampled at a rate of 15 Hz. Is the Nyquist theorem violated

Sati [7]

Answer:

Fs = 15 Hz > 12.7322 Hz

Hence, Nyquist theorem is NOT violated

Step-by-step explanation:

Given that;

a signal given by 15cos(20t) + 20sin(40t)

sampled at a rate of 15 Hz

Is the Nyquist theorem violated?

so;

from 15cos(20t) + 20sin(40t)

Freq F1 = 20/2π Hz

F1 = 3.1830 Hz

and

Freq F2 = 40/2π

F2 = 6.3661 Hz

Now, Nyquist's rate FN ≥ 2 × F_max

FN ≥ 2 × 6.3661

FN ≥ 12.7322 Hz

Now our given signal was sampled at a rate of 15 Hz

so, Fs = 15 Hz > 12.7322 Hz

Hence, Nyquist theorem is NOT violated

Expand each binomial. (2y-z)^5

Stels [109]

$(2y-z)^5=(2y-z)^2\cdot(2y-z)^3 \\(4y^2-4yz+z^2)\cdot(8y^3-12y^2+6yz-(-z)^3) \\(4y^2-4yz+z^2)\cdot(8y^3-12y^2+6yz-z) \\\boxed{32y^5-48y^4+24y^3z-4y^2z-32y^4z+48y^3z-24y^2z^2+4yz^2+8y^3z^2-12y^2z^2+6yz^3-z^3} \\$

The required number will be 16

the expression will be like :

$9 {x}^{2} + 24x + 16$

$(3x) {}^{2} + (2 \times 3x \times 4) + (4) {}^{2}$

$(3x + 4) {}^{2}$

hope it helps you cap !!
