Question

Consider the cascade of two filters with frequency responses

H 1 ( j Ω ) = j Ω

H 2 ( j Ω ) = 1 e^{ - j Ω}

(1) Indicate what each of the filters does.

(2) Suppose that the input to the cascade is

x ( t ) = p ( t ) cos ( πt / 2 ) , w h e r e p ( t ) = u ( t + 1 ) - u ( t - 1 ).

Find the output y(t) of the filter.

(3) Suppose we cascade the above filter by putting first H 2 followed by H1. Does the response change? Explain.

The frequency response H(f) of a linear system
is given by: , where f is frequency in Hz.
(repeat - y(f)/x(f) = H(f) = j2f )
Find the output y(t) of this system for a 10 Hz cosinusoidal
input with an an amplitude of 3, i.,e
. Again (x(t) = 3*cos(2*pi*10*t)
A.) y(t) = 60*cos[2pi10t + (pi/2)]
B.) y(t) = j60cos(2*pi*10t)
C.) y(t) = 3*cos(2pi*60*t)
D.) y(t) = 60*cos[2*pi*10*t - (pi/2)]

y[n] =b(ax[n] +x[n-1]+ax[n-2]) where a&b >0.
Find the frequency response of the system H(e^jw). Determine the
values of a & b, if the magnitude response of the filter at w =
0 is 1 and at w =pi÷2 is 0.5.

if the transfer function H(z) of a stable LTI system
has two zeros at z =1+j and z = 1-j and two poles at z = 0 and z =
-0.5. Write the expression of H(z), if the frequency response of
the system at omega (w) where w = 0 is 1.
can I have help here ?

A linear time invariant system has an impulse response given by

Consider permutations of the 26-character lowercase alphabet
Σ={a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z}.
In how many of these permutations do
a,b,c occur consecutively and in that
order?
In how many of these permutations does a appear before
b and b appear before c?

ANSWER IN C++ ONLY
A string of characters including only alphabets (lowercase
letters) is provided as an input.
The first task is to compute the frequency of each character
appearing in the string. In the output, the characters have to be
arranged in the same order as they appear in the input string.
Then characters have to be rearranged, such that all the
characters having a specific frequency, say xx, come together.
Let the frequency of a character, lying in...

C Programming
I am trying to also print the frequency and the occurrence of an
input text file. I got the occurrence to but cant get the
frequency.
Formula for frequency is "Occurrence / total input
count", this is the percentage of occurrence.
Can someone please help me to get the frequency to work.
Code:
int freq[26] = {0};
fgets(input1, 10000, (FILE*)MyFile);
for(i=0; i< strlen(input); i++) {
freq[input[i]-'a']++;
count++;
}
printf("Text count = %d", count);
printf("\n");
printf("Frequency of plain text\n");...

An ac circuit consists of a 1.00 x 102 Ω resistor, a 1.00 x 10-1
H inductor, and a 1.00 x 10-5 F capacitor connected in series with
each other and with a generator that supplies a voltage ΔVT = 140 V
sin (500t + φ ).
1. Find the following quantities: (a) the impedance, (b)
the rms current, (c) the rms voltage drops across the: resistor,
inductor and capacitor (d) the average power loss, (e) the phase
angle, (f)...

1. Write a MATLAB function to determine the discrete-time
Fourier Transform (H(?)) of the following sequence. Plot its
magnitude and phase. You can use the dtft command and use the abs,
angle and plot commands to plot the results.
x(n) = {4, 3, 2, 1, 2, 3, 4}.
2. Analytically determine H(z) and plot its magnitude and phase
for the following system using freqz.
y(n) = 2x(n) + x(n ? 1) ? 0.25y(n ? 1) + 0.25y(n ? 2).
