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.

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");...
