A moving coil galvanometer consists of a coil in a uniform magnetic field Bo, suspended fro a fibre of torque constant C, current I produces a deflection O=nABoi/c where n is the number of turns and A is the area of the coil. The period of oscillation T=2?(I/C)1/2 where I is the moment of inertia. The resistance of the coil and the circuit in which it is placed is adjusted to give a critical dumping Rc=n2 A2Bo2/2(ic)1/2 . if the minimum detectable current produces deflection equal to thermal -root mean square value O, show that minimum current is given by
imin =( ?KT/ TRc)1/2
Q. How can a JFET be used as a constant current source? Explain from the drain characteristics. As the VDS voltage is increased from 0 to a few volts, the current will increase
Q. Why positive feedback is used in oscillator? The main application of positive feedback is in oscillators. An oscillator generates AC output signal without any input AC signa
Q. Discuss the nature of sinusoidal signal? Discuss the nature of evenness and oddness of: (a) The sinusoidal signal x(t) = A cos(2πf 0 t + θ). (b) The complex exponentia
