A voltage amplifier without feedback has a nominal gain of 500. The gain, however, varies in the range of 475 to 525 due to parameter variations. In order to reduce the per-unit change to 0.02, while maintaining the original gain of 500, if the feedback is introduced, find the new direct transfer gain G and the feedback factor H.
State and prove parallelogram law of forces and explain it''s applications
Flag Registers Flag register is also an 8 bit register. Out of 8 bit five are defined as flags to indicate status of the accumulator hence it is also called status reg
Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 4
Q. What are the features of clamping circuits? The clamping circuit does not change the peak to peak or r.m.s value of the waveform .Thus the input waveform and clamped output
Q. Draw and explain diode clipping circuit ? A diode clipping circuit can be used to limit the voltage swing of a signal. Clipper circuits are used to clip a portion of the w
Quite often an amplifier is used as a component of an amplifier circuit. Consider the amplifier circuit shown in Figure, which contains an amplifier block as an internal component.
Q. What is Autotransformers? In contrast to a two-winding transformer, the autotransformer is a single-winding transformer having a tap brought out at an intermediate point. Th
Q. Explain AC voltage controllers? Common applications for these controllers are found in fan, pump, and crane drives. Figure shows three-phase symmetrical ac voltage-controlle
can you please briefly explain about significance of the word direction in vectors with some valid points
