A TRF receiver is to be designed with a single tuned circuit using an 8.2 uH inductor. If the frequency is to be tuned from 55 kHz to 1600 kHz, find the BW that results at 550 kHz if there is exactly 10 kHz BW at a frequency of 1050 kHz.
a. 105 kHz
b. 15.24 kHz
c. 5.24 kHz
d. 10 kHz

Answers

Answer 1

Answer:

[tex]Bw_1=5.24kHz[/tex]

Explanation:

From the question we are told that:

Induction [tex]L=8.2uH[/tex]

Resonant Frequencies

[tex]F_1=550kHz\\\\\F_2=1050kHz[/tex]

Generally the Bandwidth & Frequency equation is mathematically given by

[tex]\frac{F-1}{Bw_1}=\frac{F_2}{Bw_2}[/tex]

Therefore

[tex]Bw_1=\frac{500}{1050}*10[/tex]

[tex]Bw_1=5.24kHz[/tex]

Answer:

equal amounts of inversion and retention at the center undergoing substitution

Explanation:

In an SN1 reaction, the rate determining step is the formation of a carbonation which is flat and planar.

This means that both faces of the carbo cation are equally available for attack by the nucleophile.

Attack on either of the faces may occur equally thereby yielding a racemic mixture.

in c the square root of a number N can be approximated by repeated calculation using the formula NG = 0.5(LG + N/LG) where NG stands for next guess and LG stands for last guess. Write a function that calculates the square root of a number using this method. The initial guess will be the starting value of LG. The program will com- pute a value for NG using the formula given. The difference between NG and LG is checked to see whether these two guesses are almost identical. If they are, NG is accepted as the square root; otherwise, the next guess (NG) becomes the last guess (LG) and the process is repeated (another value is computed for NG, the difference is checked, and so on). The loop should be repeated until the difference is less than 0. 005. Use an initial guess of 1. 0. Write a driver function and test your square root function for the numbers 4, 120. 5, 88, 36.01, 10,000, and 0. 25

Answer:

Following are the program to the given question:

#include <stdio.h>//header file

double square_root(double N, double initialGuess)//defining a method square_root that takes two variable in parameters

{

double NG, LG = initialGuess,diff;//defining double variable

while(1)//use loop to calculate square root value

{

NG = 0.5 * (LG + N / LG);//using given formula

diff = NG - LG;//calculating difference

if(diff < 0)//use if to check difference is less than 0

diff = -diff;//decreaing difference

if(diff < 0.005)//use if that check difference is less than 0.005

break;//using break keyword

else//defining else block

{

LG = NG;//holding value

}

return NG;//return value

}

int main()//defining main method

{

double ans, n,initialguess = 1.0;//defining double variable

n = 4;//use n to hold value

ans = square_root(n, initialguess);//calculating the square root value and print its value
