Short example sentences

Noise temperature of an amplifier chain The noise temperature of an amplifier is commonly measured using the Y-factor method. (20 words)

Thus it doesn't make sense to talk about the noise temperature of a capacitor or of a voltage source. (20 words)

In electronics, noise temperature is one way of expressing the level of available noise power introduced by a component or source. (21 words)

Longer example sentences

In the usual case where the gains of the amplifier's stages are much greater than one, then it can be seen that the noise temperatures of the earlier stages have a much greater influence on the resulting noise temperature than those later in the chain. (46 words)

If that amplifier is used to amplify a source having a noise temperature of about room temperature (290 K), as many sources do, then the insertion of that amplifier would reduce the SNR of a signal by 6 dB. (39 words)

The noise temperature of an amplifier refers to the noise that would be added at the amplifier's input (relative to the input impedance of the amplifier) in order to account for the added noise observed following amplification. (38 words)

Example sentences (16)

The noise factor is defined as the ratio of the output noise power of a device to the portion thereof attributable to thermal noise in the input termination at standard noise temperature T 0 (usually 290 ).

For example, a satellite antenna may not receive noise contribution from the earth in its main lobe, but sidelobes will contribute a portion of the 290K earth noise to its overall noise temperature.

The antenna noise temperature depends on antenna coupling to all noise sources in its environment as well as on noise generated within the antenna.

The noise temperature of an amplifier refers to the noise that would be added at the amplifier's input (relative to the input impedance of the amplifier) in order to account for the added noise observed following amplification.

In those cases a reference to the amplifier's noise temperature itself, rather than the noise figure defined according to room temperature, is more appropriate.

Noise temperature of an amplifier chain The noise temperature of an amplifier is commonly measured using the Y-factor method.

The physical temperature of the antenna generally has little or no effect on The noise temperature of the receiver circuitry represents noise generated by noisy components inside the receiver.

In electronics, noise temperature is one way of expressing the level of available noise power introduced by a component or source.

In the usual case where the gains of the amplifier's stages are much greater than one, then it can be seen that the noise temperatures of the earlier stages have a much greater influence on the resulting noise temperature than those later in the chain.

Speaking of noise temperature therefore offers a fair comparison between components having different impedances rather than specifying the noise voltage and qualifying that number by mentioning the component's resistance.

Effectively the noise temperature of the amplifier has been quadrupled, in addition to the (smaller) contribution due to the attenuator itself (usually room temperature if the attenuator is composed of resistors ).

If that amplifier is used to amplify a source having a noise temperature of about room temperature (290 K), as many sources do, then the insertion of that amplifier would reduce the SNR of a signal by 6 dB.

If there are multiple amplifiers in cascade, the noise temperature of the cascade can be calculated using the Friis equation : McClaning, Kevin, and Tom Vito.

Note that one can only speak of the noise temperature of a component or source whose impedance has a substantial (and measurable) resistive component.

On the other hand a good satellite dish looking through the atmosphere into space (so that it sees a much lower noise temperature) would have the SNR of a signal degraded by more than 6 dB.

Thus it doesn't make sense to talk about the noise temperature of a capacitor or of a voltage source.
