It is related to damping in the circuit using a resistor.

Q is inversely proportional to the resistor(R).

So if the value of resistance is high, there is a greater damping and the value of Q will be low.

if resistance is low, there is small damping and Q will be high.

when Q is high(low damping) the graph of voltage across resistor against frequency will be sharp at resonance and the bandwidth will be small

when Q is low(high damping) thee graph will be less sharp as the bandwidth will be large.

Go do some research on the graphs and the formula of Q factor to understand it better.

This appears to be a Motorola diode, and a data sheet is available from that company.

An amplifier can be made into an oscillator by feeding back part of the output to the input.

A simple oscillator uses a Frequency Determining Network (FDN) in the feedback path to give a predictable frequency of oscillation.

There are some simple requirements - the valve must be capable of operating at the desired frequency, and the total gain (loop gain) from output to input must be at least unity.

Many oscillators use tuned inductive-capacitive circuits, but it's also possible to use a resistive-capacitive circuit, or a quartz crystal as the FDN.

FETs can be called UNIPOLAR devices because the charge carriers that carry the current through the device are all of the same type i.e. either holes or electrons, but not both. This distinguishes FETs from the bipolar devices in which both holes and electrons are responsible for current flow in any one device.

The difference between linear and non-linear PCM is LPCM represents sample amplitudes on a linear scale. LPCM specifies that the values stored are proportional to the amplitudes, rather than representing say the logarithm of the amplitude or being related in some other manner. While non-linear each step size may vary in amplitude.

The total power equals the sum of the individual powers because power is the rate at which energy is supplied. Whether you have a series or parallel circuit, the total power comes from the power source.

The average value of a sine wave is 0. That's by integrating the function over a whole (or any integer number of whole-) cycles and dividing by the total time, n*T.

In a "pure" sine wave, i.e., one with zero distortion, one half cycle has some total integral that's a sum of positive values, while the second half cycle is all *below the axis*, so negative in value and symmetrical with the first half. So when you add the two (or n*2) half cycles--which is integration--you get a sum of zero. No matter the frequency, or amplitude of the sine wave.

It is nasty that nups tries to market barking silencers when they marally should intall silencers on their brown trucks. FEDEX does.

Voltage is synonymous with 'potential difference', and cannot have a positive or negative value (in the sense of charge). So what you are describing is 'potential', which can. So, for example, a battery whose positive terminal is earthed or grounded will indicate a negative potential if a voltmeter is connected between earth and its negative terminal.

Output voltage swing is defined as the maximum positive or negative peak output voltage that can be obtained without wave form clipping, when quiescent DC output voltage is zero.

VOM is limited by the output impedance of the amplifier, the saturation voltage of the output transistors, and the power supply voltages. This is depicted in the figure below.

This emitter follower structure cannot drive the output voltage to either rail. Rail-to-rail output op amps use a common emitter (bipolar) or common source (CMOS) output stage. With these structures, the output voltage swing is only limited by the saturation voltage (bipolar) or the on resistance (CMOS) of the output transistors, and the load being driven.

Maximum and minimum output voltage is usually a design issue when dynamic range is lost if the op amp cannot drive to the rails. This is the case in single supply systems where the op amp is used to drive the input of an ADC, which is confiured for full scale input voltage between ground and the positive rail.

q = C x V, The amount of charge on each plate is equal and the same as q.

So: q = 0.000004 x 12 = .000048 or 48 uQ

the impedence should be complex conjugate of an equivalent impedence of the network when viewed from the terminals of the load.

i.e; Z=R-jx

The anod terminal of diode is connected with negative and cathod is connected to positive

Open circuit test on a transformer is usually performed to measure the IRON losses.Iron losses are produced due to eddy current and hysteresis losses. In open circuit test, the LV side, generaly the secondary winding, is kept open and the HV side, generaly the primary winding is fed with the rated voltage and frequency. The rated voltage is applied in order to setup normal flux in the transformer, which in return further produces the normal iron losses at rated voltage. the wattmeter connected at the primary side will show the power consumed due to iron losses. this calculation further utilized for determing the efficiency of transformer.

No, value of output voltage depends upon the value of input voltage and digital can not produce the same output voltage for different input values.

For example, suppose in a digital circuit two switches are connected. A closed switch is represented by 1 and an open one by 0. If there are two switches and we say that they are in state 1, then it would mean that both of them are closed. In this circuit after connection with the battery some current would pass so we call this current as output.Depending upon the states of the switches, the current either would pass or it would not pass.In case the current is passing, we can say the value of output is 1 and it is 0 when no current is passing. Whether the value of the output would be 1 or 0, it depends upon the values of input variables( 1 and 0) which specify the state of the switches.In this example, the switches form the input variable because the value of output depends upon the state of these variables which shows that digital circuit can not produce same output voltage for different values of input voltage.

yes

Analog way. Unless you have a digital thermometer

Potential Difference across a resistor is given by,

Potential Difference = Resistance * Current

Which is true of a series circuit that has two resistors?A.The resistors are on different branches of the circuit.B.Neither resistor has current flowing through it.C.One resistor has no voltage across it.D.Both resistors have current flowing through them.

IC741 has a low slew rate because of the predominance of capacitance present in the circuit at higher frequencies. As frequency increases the output gets distorted

due to limited slew rate.
