Draw the implementation of time-invariant system
A linear time-invariant system is described by the difference equation:
y[n] = 2x[n] - 3x[n - 1] + 2x[n - 2]
Draw the implementation of this system as a block diagram.
Define Series VAr Compensation? For very long transmission lines, the inductive reactance of the line becomes so high that not much power can be transmitted through the line, s
Q. If the output signal fromanAMmodulator is given by u(t) = 5 cos 1800 πt + 20 cos 2000 πt + 5 cos 2200 πt , determine: (a) The modulating signal m(t) and carrier c(t). (b)
write a note on vulcanization
Q. Consider the 4-bit R-2R ladder D/A converter with V ref =-10 V. Determine the analog output voltage when the binary input code is 1100. Also, find what reference voltage is to
A transistor has (A) One p-n junction. (B) Two p-n junction. (C) Four p-n junction. (D) Five p-n junction. Ans: A transistor has two p-n junctions.
Q. Give a general account of common drain amplifier? The output is taken over the source terminal and when the dc supply is replaced by its short circuit equivalent, the drain
History - Field-Effect Transistor: The principle of field-effect transistors was very first patented by Julius Edgar Lilienfeld in the year 1925 and by Oskar Heil in the year
Q. Show NPN Common Collector Amplifier? The common collector amplifier, often called an emitter follower since its output is taken from the emitter resistor, is useful as
Q. A dc series motor, with a design constant K a = 40 and flux per pole of 46.15 mWb, operates at 200 V while taking a current of 325 A. The total series-field and armature-circui
The output port of the one-port is defined by terminals A and B. Given: R 1 = 10 k_, R 2 = 20 k_, R 3 = 10 k_, and R 4 = 10 k_ V 1 = 20 V and I1 = 0.8 mA a) Find the T
