Signal Class

An immutable data structure which represents the properties of a single signal consisting of a power, center frequency, bandwidth range, noise temperature, noise bandwidth range, and a set of additional objects representing additional data. The additional data is identified by type and is used to represent things like message data encoded on the signal, DigitalModulation, SignalDataRate, etc.

Properties
  NameDescription
Public propertyBandwidth
Gets the signal bandwidth, in hertz. This specifies the range of frequencies over which the majority of signal Power is distributed.
Public propertyStatic memberBaseSignal
Gets an instance of a signal with zero power, zero frequency, and infinite bandwidth.
Public propertyFrequency
Gets the center frequency of the signal, in hertz. This is usually the frequency which has the greatest power density.
Public propertyLowerBandwidthFrequency
Gets the lower bandwidth frequency, in hertz. This specifies the signal's lowest frequency.
Public propertyLowerBandwidthLimit
Gets the offset from the center Frequency to the lower bandwidth limit, in hertz. (Usually, this value is negative).
Public propertyLowerNoiseBandwidthFrequency
Gets the frequency of the lower boundary of the noise bandwidth, in hertz. This specifies the lowest frequency at which there is significant noise.
Public propertyLowerNoiseBandwidthLimit
Gets the offset from the center Frequency to the lower limit of the noise bandwidth, in hertz. (Usually, this value is negative).
Public propertyNoiseBandwidth
Gets the bandwidth of the signal noise, in hertz. This specifies the range of frequencies over which there is significant noise.
Public propertyNoisePower
Gets the power of the noise, in watts, as computed from the NoiseTemperature based on the NoiseBandwidth.
Public propertyNoiseTemperature
Gets the equivalent noise temperature, in kelvin. This represents the contribution of thermal noise and other stochastic processes on the signal.
Public propertyPower
Gets the total signal power, in watts. This specifies the total power spread out over the Bandwidth.
Public propertyUpperBandwidthFrequency
Gets the upper bandwidth frequency, in hertz. This specifies the signal's highest frequency.
Public propertyUpperBandwidthLimit
Gets the offset from the center Frequency to the upper bandwidth limit, in hertz.
Public propertyUpperNoiseBandwidthFrequency
Gets the frequency of the upper boundary of the noise bandwidth, in hertz. This specifies the highest frequency at which there is significant noise.
Public propertyUpperNoiseBandwidthLimit
Gets the offset from the center Frequency to the upper limit of the noise bandwidth, in hertz.

Methods
  NameDescription
Public methodAddAndRemoveExistingDataT
Creates a new signal by adding data in addition to the data existing on this signal. Existing instances of the supplied data type will be removed.
Public methodAddData
Creates a new signal by adding data in addition to the data existing on this signal.
Public methodAddNoiseTemperature
Creates a new signal by adding noise temperature (such as thermal noise), in kelvin.
Public methodApplyGain
Create a new signal by applying a gain to this signal. The gain is applied to both the signal Power and NoisePower.
Public methodStatic memberCreateSignal(Double, Double, Double, Double)
Create a new noiseless signal based on the given properties.
Public methodStatic memberCreateSignal(Double, Double, Double, Double, IEnumerableObject)
Create a new noiseless signal based on the given properties.
Public methodStatic memberCreateSignal(Double, Double, Double, Double, Double, Double, Double)
Create a new signal based on the given properties. Note: This method should NOT be used as a way to modify a pre-existing signal. Use ModifySignalProperties(Double, Double, Double, Double, Double, Double, Double) or similar methods on the pre-existing signal instance.
Public methodStatic memberCreateSignal(Double, Double, Double, Double, Double, Double, Double, IEnumerableObject)
Create a new signal based on the given properties.
Public methodEquals(Object)
Returns true if this signal is equivalent to the given object.
(Overrides ObjectEquals(Object).)
Public methodEquals(Signal)
Returns true if this signal is equivalent to the other signal.
Protected methodFinalize

(Inherited from Object.)
Public methodGetDataByType(Type)
Get signal data based on the type of data requested. This data represents optional properties on the signal.
Public methodGetDataByTypeT
Get signal data based on the type of data requested. This data represents optional properties on the signal.
