The operating frequency range of a superheterodyne FMreceiver is 88-108MHz. The IF and LO frequencies are so chosen that fIF LO.Ifthe image frequency f c must fall outside of the 88- 108-MHz range, determine the minimum needed f IF and the corresponding range of f LO.
Q. (a) Consider the capacitor - input filter circuit of Figure and obtain the z-parameters for the circuit. (b) Determine the transfer function V 2 /V 1 when I 2 is zero.
Saturation or active mode While V GS > V th and V DS > (V GS - V th ) The switch is turned on, and a channel has been made that allows current to flow
Q. How oscillations start up in an oscillator? The noise voltage produced due to the random motion of electrons in resistors or in active devices provides the starting voltage
Q. Explain the transfer characteristics in a few words ? The transfer characteristics are a plot of an output (or a drain) current versus an input controlling quantity. There i
what is zeenar doide and explain its working
I need help in Simulink model (.mdl) (discrete) for the topic “sensorless control of the pmsm using Back EMF method” with detailed explanation of the estimator (Back EMF method).
A zener regulator consumes a zener diode with an internal zener resistance of 5 ohm and the value of resistance in the regulator circuit is 82 ohm. If the supply voltage alters by
Q. Determine the open-circuit output voltage v o of the system shown in Figure as a function of the input voltage v i .
advantages and disadvantages of direct and r c coupling
a) A 230 V/25V, 50 HZ transformer with a rated primary current of 1,2 Amps is used to supply a number of 25 V, 30 Watt halogen light bulbs. Assuming an ideal transformer and tha
