(a) For a series RLC resonant circuit, find an expression for the voltage across the resistance VR and obtain the ratio VR/VS, where VS is theapplied voltage. Identify the expressions for the series resonant frequency and bandwidth.
(b) Determine the resonant frequency and bandwidth, given the voltage transfer function to be 103 /(s2 + 103s + 1010).
Q. Why we Need biasing? Need for biasing : Baising is necessary to establish the quiescent operating point so that the device operates with the linear region without exceeding
Q. An 8 - pole dc generator has 500 armature conductors and has a useful flux per pole of 0.065 web. What will be the emf generated if it is lap connected and runs at 1000 r.p.m.
how to derive its transfer function
Q. How can a JFET be used as a voltage controlled resistor. Explain from drain characteristics? The region to the left of the pinch off locus is referred to as the ohmic region
Q. The unit impulse response h(t) of a linear system is h(t) = 5e -t cos(2t - 30°). Determine H(s).
Q. A magnetic force exists between two adjacent, parallel current-carryingwires. Let I1 and I2 be the currents carried by the wires, and r the separation between them.
