Homework 11
THOSE ANSWER ARE ABSOLUTELY CORRECT...
@aditya07 Tell me question
Parallel resonant "tank" circuits are common in radio equipment. But unfortunately there is always resistance that prevents them from being perfect: in every real inductor, the wire that makes up the inductance has some resistance, and there may be leakage in the capacitor that can be modeled as a resistance. Also, the Norton resistance of the system connected to the tank circut looks like a leakage through the capacitor. So a realistic model for a tank circuit is the following: In the space provided below write an algebraic expression in terms of the device parameters for the bandwidth Δω of the impedance Z looking into this tank circuit.
The antenna tank of a Graymark 536 Radio Kit has an inductance L≈0.65mH. The resistance of the inductor RL≈4.0Ω. The equivalent resistance across the capacitor is RC≈490.0kΩ. The capacitor is variable, for tuning. If we tune to a station at f=830.0kHz what is the capacitance, in picoFarads, of the tuning capacitor?
What is the bandwidth, in kHz, of the tank at f=830.0kHz?
What is the bandwidth, in kHz, of the tank at f=980.0kHz?
7.5 is showing wrong for me
If next we tune to a station at f=1270.0kHz what is the capacitance, in picoFarads, of the tuning capacitor??
If next we tune to a station at f=1270.0kHz what is the capacitance, in picoFarads, of the tuning capacitor??
AND 8.5 IS SHOWING ME WRONG TOO BRO:)
again for f=1570khz??
n tell me the bandwidth 2
What is the bandwidth, in kHz, of the tank at f=1270.0kHz?
If next we tune to a station at f=1600.0kHz what is the capacitance, in picoFarads, of the tuning capacitor? incorrect What is the bandwidth, in kHz, of the tank at f=1600.0kHz?
plz tell me If we tune to a station at f=740.0kHz what is the capacitance, in picoFarads, of the tuning capacitor?
What is the bandwidth, in kHz, of the tank at f=1270.0kHz?
What is the bandwidth, in kHz, of the tank at f=650.0kHz
@Nurali: can u tell me the procedure???
What is the bandwidth, in kHz, of the tank at f=1600.0kHz?
What is the bandwidth, in kHz, of the tank at f=1270.0kHz? ???
:( 27 IS GIVING ME A CROSS I MEAN F=1600 KHZ
What is the bandwidth, in kHz, of the tank at f=740kHz? ???
hw11 p3 From the voltage graphs given above, estimate the Q of the second-order system. Enter your estimation in the space provided below. (Hint: the answer is an integer).???

Please tell me the answer of Last Question of H11P3
zinda bad Nurali...22 is right answer for f=1600 khz
What is the bandwidth, in kHz, of the tank at f=1480.0kHz?
thanks man it was 18.3
H11P1 1)1/(RC*C) + RL/L 2)use these formulas a)C=1/(ω2L) b)ω=2πf for me,with L=0.65 and f=680.0, i calculated the value which i got as 8.4 and the answer is 84 3)use formulae in 1 4)Do the same as 2
1/w2L ,where 2 means squared......c u all tmrw..im off
H11P2 1)VM=.7v VM * 0.1 = 0.07 V 2)cp= 22/9=2.4 3)yet to do 4)0.1*VM(t)=.8v
The oscilloscope is used to measure and display waveforms at many frequencies. Suppose that VM=0.08cos(2π 147.0×106 t) V. What is the value, in picoFarads, that Cp should be set to so that Vs=0.008V?
