Question 821461: been trying to figure this out for 2 days now.
26. When an r-f tank is operating within 10 per cent of its resonance frequency, the impedance of the tank can be found by the formula
"Z= Zr divided by the square root of 1+4Q^2(F-Fr/Fr)^2 "
where z,. is the impedance of the tank at resonance, F is the operating frequency, and FR is the resonant frequency. What is the impedance
of the tank if its impedance at the resonant frequency, 150MHz, is
60,000ohm and the Q of the tank is 125? The tank is operating at
142.5 MHz. F and FR are in hertz and Zr is in ohms.
... for some reason my formula won't copy. so i put it in " "
