A Band pass filter is the filter which passes the frequencies within the given range of frequencies and rejects the frequencies which are outside the defined range. The Butterworth band pass filter designed to have the frequency response flat as much as possible to be in the pass band. The following are the specifications of the digital band pass butter worth filter. The sampling rate of the filter is around 40 kHz. The pass band edge frequencies are in the range of 1400 Hz to 2100 Hz. The stop band edge frequencies are within the range of 1050 Hz ... Read More

Hermite_e series is also known as probabilist's Hermite polynomial or the physicist's Hermite polynomial. It is available in mathematics which is used to calculate the sum of weighted hermites polynomials. In some particular cases of the quantum mechanics, the Hermite_e series the weight function is given as e^(−x^2). Calculating Hermite_e series The following is the formula for Hermite_e series. H_n(x) = (−1)^n\:e^(x^2/2)\:d^n/dx^n(e^(−x^2/2)) Where, H_n(x) is the nth Hermite polynomial of degree n x is the independent variable d^n/dx^n denotes the nth derivative with respect to x. In Numpy library we have the function namely, polynomial.hermite.hermder() to ... Read More

The aim of this article is to implement a program Minimize count of alternating subsequences to divide a given binary string with subsequence number. Here, you are provided with a binary string as part of the issue. In order to prevent any subsequence from including adjacent zeros and ones, we must reduce the number of subsequences and output the subsequence number that corresponds to each string element. A subsequence represents a sequence which can be created by taking the supplied sequence and eliminating zero or more members while maintaining the initial position of the elements that remain. Input Let ... Read More

The aim of this article is to implement a program maximum count of characters that can replace? by at most A 0s and B 1s with no adjacent duplicates. Given a couple of integers A and B, both of which that represent the number of 0s and 1s that are accessible, and a string Str with only the special characters "*" and "?" The aim is to determine the greatest number of characters that may be used in the '?' position without causing any neighboring characters to be identical. Example 1 Let us give the input string str = ... Read More

The aim of this article is to implement a program to Position the leftmost set bit in a given binary string where all 1s appear at the end. A string of bits is known as a binary string. A binary string is utilized for storing non-traditional data, such as images, as opposed to a character string, which typically holds text data. The quantity of bytes in a binary string determines its length. Binary data, or data that is portrayed in a binary (base-2) version instead of a text (base-10) format, is stored in binary string variables in computer programming. ... Read More

To find the largest string formed by choosing words from a given sentence, a user should know about the lexicographically largest string. A lexicographically largest string is a string, when sorted alphabetically, it would appear at the last if we form all possible strings from the selected words. For example: {lion, zebra, apple} will be lexicographically sorted as {apple, lion, zebra}. In this article, we have been given a string and a pattern. Based on this pattern, we have to find the lexicographically largest string matching the given pattern by choosing words from the sentence using C. Here is an ... Read More

The aim of this article is to implement a program to find the count of alphabetic and alphanumeric strings from a given array of strings. As we know, a string is a group of characters that ends with the null character "\0" in C programming. Characters from the C string are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0." Input arr[] = {“snmd”, “nej7dnr”, “snmd”, “dltmdj”, “lbwm2p6”} Output 3 2 “snmd”: 2 “nej7dnr”: 1 “dltmdj”: 1 “lbwn2p6”: 1 Explanation The strings ... Read More

The aim of this article is to implement a program to obtain the count of sum of “10” subsequences for each 1 in string with A 1s, B 10s and C 0s. Example Let us take the Input: A = 1, B = 2, C = 3 Output obtained here is : 14 Explanation A = 1 denotes. There is a single "1" string, B = 2 denotes, there is a pair of "10" strings, and C = 3 denotes, there is a trio of "0" strings. The string that results from concatenation is "11010000". Five ...

The aim of this article is to implement a program to convert a string Str1 to Str2 by moving B to right and A to left without crossover. As we know, a string is a group of characters that ends with the null character "\0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0". Example Let us take the input strings, str1 = “#B#A#”, and str2 = “##BA#” Output obtained here is: Yes Explanation − 'B' ... Read More

The aim of this article is to implement a program C++ program to check if all rows of a matrix are circular rotations of each other. Here is a small glimpse on what a matrix exactly is. The rectangular array of symbols or numbers organized in rows and columns is known as a matrix. A matrix can be of many distinct types, including row, column, horizontal, vertical, square, diagonal, identity, equal, and singular. Addition, subtraction, as well as multiplication are the three fundamental matrix operations. The goal is to determine whether all rows of a matrix of size n*n ... Read More
