Which encoding method uses alternating positive and negative values for 1s?
The encoding method that uses alternating positive and negative values for 1s is called Alternate Mark Inversion (AMI). In AMI, binary 0s are represented by a zero voltage level, while binary 1s are represented by alternating positive and negative voltages, which helps to maintain a balanced signal and reduces the likelihood of long runs of zeros. This technique is commonly used in digital communication systems to ensure reliable data transmission.
You are wiring a LED lamp through a transformer you have a polarized plug and you know positive and negative The transformer is marked live and neutral Does live correspond with positive or negative?
LED's are DC voltage. Transformers are AC voltage. There is no positive or negative on AC voltage. You would need a diode to change the AC to DC, then there would be positive and negative voltages.
Positive logic in a logic circuit is one in which?
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.Both voltage states could be positive, both could be negative, or they could be opposite polarities.
How do you calculate positive negative and zero sequence impedance?
Positive, negative, and zero sequence impedances are calculated using the sequence components of the system's phase currents and voltages. For a three-phase system, you can express the phase currents and voltages in terms of their sequence components using the transformation matrix. The positive sequence impedance is derived from the phase impedances during balanced conditions, while negative and zero sequence impedances are calculated using the same method under unbalanced conditions, typically by analyzing the system's response to faults or imbalances. These impedances are essential for studying fault conditions and system stability in power systems.
What signals represent information with a sequence of 0s and 1s?
Signals that represent information using a sequence of 0s and 1s are typically digital signals. These signals can be in the form of electrical voltages, light pulses, or radio waves, where specific states (high/low voltage, on/off light, or presence/absence of a wave) correspond to binary digits. Digital encoding techniques, such as pulse-code modulation or binary phase-shift keying, are often used to transmit this binary information over various communication channels.

Define a direct short?
When there is a connection across both the positive and negative voltages.
How does DSU convert binary data pulses it receives from DTE?
the DSU converts the binary data pulses it receives from the DTE to the line encoding format required by the network, withing the computer the one bits are positive voltages, and zero bits are not voltages or low level voltages.
Why are both negative and positive voltages generated as the magnet passes through the coil?
In this context, 'negative' and 'positive' are used to indicate the sense, or direction, of the induced voltages, as voltages do not have electric polarity (+ or -). The direction of the voltage induced into a conductor is determined by the direction of that conductor relative to the magnetic field. As the coil rotates, the directions of each side of the coil reverse relative to the field, and the induced voltages reverse too.
What is analog rail?
The positive and negative supply voltages. Analog amplifiers clip a few volts short of their voltages, so these two supplies are usually 12 volts or more.
What do you Mean dual tracking power supply?
It's a power supply with a positive and negative voltage, where one of the voltages tracks the other. For example: the negative voltage tracks the positive. If you regulate the positive to 15v, the negative is going to be -15v. This allows very precise symmetric power.

When a device uses two batteries why do they have to be placed positive to negative?
Batteries placed in series (which is what you're describing) add their voltages together. Thus two 1.5 volt batteries give 3 volts in series ... IF they point in the same direction. If they point in opposite directions, you get zero volts.
Does an oscilloscope display both positive and negative voltage?
Yes. By convention, the horizontal line is deflected upward for positive voltages and down for negative. With no input, adjust the line to co-incide with a central line on the graticule. A varying voltage that remains positive will be deflected above the line. A voltage that transits from positive to negative will draw above and below the line.
