depends on whether you would like calculate or measured results. if you want calculated resulted, then your best bet would be to use an oscilloscope. if you want calculated results, then there are formulas for finding out the voltage, current, impedance, and individual results from each component using the capacitive reactance, voltage, and type of transistor. are you using a summing transistor, inverting amplifying transistor, amplifying transistor, or a different transistor? also are you using DC or AC voltage or current? you need to tell me what type of transistor you are using?

Why is the gain and bandwidth of a ce-cb cascode amplifier greater than a ce amplifier?
Gain of ce-cb cascode is nearly equal to the gain of ce amplifier, because in a ce-cb cascode, the gain of the ce stage is equal to 1, and the gain of the cb stage is nearly equal to an isolated ce amplifier. Hence, gain of both are nearly equal. On the other hand, Bandwidth of ce-cb cascode is much higher than the bandwidth of ce amplifier because the cb stage in the cascode configration is not subjected to any Miller effect, thereby improving the high frequency response. The absence of Miller effect is due to the fact that the base of the cb stage is grounded thus, shielding the collector signal from being fed back into the emitter input. To be more clear, the gain of CE stage in cascode is nearly 1, which reduces the miller effect on the cb stage greatly.
Advantages of carry look ahead adder?
You use a look ahead carry adder to reduce the propagation delay effects caused by the ripple carry that would otherwise be used. With ripple carry, each stage is dependent on the preceding stage, and this is cumulative. With look ahead carry, the carries are computed in parallel, speeding up the overall process.
Link coupling is used in r-f amplifiers to?
Link coupling is used to transfer energy between two r-f circuits which for whatever reason cannot be located near to each other. The method used in link coupling is a wire loop which stretches between the two stages, terminating at each end in a coil of few turns. At the output of the first stage, this wire loop will act as a step-down transformer, and at the input of the next stage it will act as a step-up transformer. To work in this manner the loop terminations must be positioned next to the inductor of the r-f tank circuit.
What is the difference between Value Management and Value Engineering?
Value analysis is "A Systematic and objective evaluation of the value of a goods or service, focusing on analysis of function relative to the cost of manufacturing or providing the items or service". value analysis provides insight into the inherent worth of final goods or service, possibly altering specifications and quality requirements that could reduce costs without impairing functional suitability. Value engineering is "Value analysis conducted at the design engineering stage of the product development process." In summary value analysis refers to the analysis of an existing product, service or administrative process while Value engineering refers to the same analysis applied to the product ,services or administrative processes that are under design and have not been finalised.
What are the function of all the 6 simple machines?
Lever is used for lifting things like a wheel barrow Wheel & Axle is used for moving things with less force like a bike Pulley used for lifting and lowering objects like stage curtains Inclined Plane is used for lifting/moving item onto a higher object like a ramp Wedge is used for splitting/cutting like a wedge or zipper Screw used for building and holding things together like bolts or screws
Working of RC coupled amplifier?
In a two stage RC coupled amplifier, the two transistors are identical and a common power supply is used. The input is provided to the first stage of the amplifier where it is amplified and this output is used as input for the second stage. This is amplied once again by the other transistor in the second stage and the final output is obtained. There will be a 180 degree phase shift after the first stage amplification which is nullified by the 180 degree phase shift of the second stage amplification.Thus, we obtain an output which is an amplified signal of the input and is in phase with the input signal.
What is the difference between single stage and multi stage amplifiers?
single stage amplifier contain only one stage transistor amplifier but multi stage contain more than one amplifier stage

What is the function of resistor in single stage amplifier?
A simple, 1 transistor single stage amplifier can be made using several resistors to bias a NPN or PNP transistor into its' linear operating region. With this done, a small voltage signal applied to the input of the amplifier will have the voltage amplified at the output in a linear fashion. I'm not sure what your question is; if this does not answer it let me know.
Difference between cascode and cascade amplifier?
cascade: the output of one amplifier stage is connected to the input of another amplifier stages, it's also connected in series. cascode: it said to be cascode, when it has one transistor on the top of another where a common emitter transistor drives a common base transistor.
What is a direct coupled amplifier?
Quite simply, it's an amplifier wherein the stages as set up so that the output of one stage is coupled directly into the input of the next stage without any wave shaping or tuninig components between them. This makes for fairly flat frequency response. A link is provided to the Wikipedia article on direct coupling.
Why you need RC coupled amplifier?
Rc coupled amplifier is used where good frequency response required. in case of multistage amplification system,To prevent resistance of one stage to come in parallel with next stage, it is used. we use capacitor as a coupling element between two consecutive stages.
Theory of RC coupled Amplifier?
In a two stage RC coupled amlifier the rransistor are identical and a common power supply is used. the output is provided to the first stage of the amplifier wher it is amplified and this output is uses as a input for the sexound stage this is amplified once again by the other transistor in the sexound stage and the final out put is obtain.
High frequency response of RC coupled amplifier?
At high frequency the capacitor coupling the stages has low reactance, therefore the net resistance of that stage is not equal to next stage, due to this poor impedance matching the power of this stage is not transferred fully to next stage and hence gain falls. And also at high frequency transistor capacitance comes into existence which provides feedback and it thus lowers gain.
How is negative feedback achieved in a single stage transistor amplifier?
A: Feedback is a signal fed back from the output like from collector to the base .
What type of transistor is used in amplifier?
Depends on the type of amplifier. There are a lot of different circuits of amplifiers and each one of them use proper transistors, that works better for that circuit. Moreover, on every stage of the amplifier are used different transistors as well.
