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

	Name	Description
	Bandwidth	Gets the signal bandwidth, in hertz. This specifies the range of frequencies over which the majority of signal Power is distributed.
	BaseSignal	Gets an instance of a signal with zero power, zero frequency, and infinite bandwidth.
	Frequency	Gets the center frequency of the signal, in hertz. This is usually the frequency which has the greatest power density.
	LowerBandwidthFrequency	Gets the lower bandwidth frequency, in hertz. This specifies the signal's lowest frequency.
	LowerBandwidthLimit	Gets the offset from the center Frequency to the lower bandwidth limit, in hertz. (Usually, this value is negative).
	LowerNoiseBandwidthFrequency	Gets the frequency of the lower boundary of the noise bandwidth, in hertz. This specifies the lowest frequency at which there is significant noise.
	LowerNoiseBandwidthLimit	Gets the offset from the center Frequency to the lower limit of the noise bandwidth, in hertz. (Usually, this value is negative).
	NoiseBandwidth	Gets the bandwidth of the signal noise, in hertz. This specifies the range of frequencies over which there is significant noise.
	NoisePower	Gets the power of the noise, in watts, as computed from the NoiseTemperature based on the NoiseBandwidth.
	NoiseTemperature	Gets the equivalent noise temperature, in kelvin. This represents the contribution of thermal noise and other stochastic processes on the signal.
	Power	Gets the total signal power, in watts. This specifies the total power spread out over the Bandwidth.
	UpperBandwidthFrequency	Gets the upper bandwidth frequency, in hertz. This specifies the signal's highest frequency.
	UpperBandwidthLimit	Gets the offset from the center Frequency to the upper bandwidth limit, in hertz.
	UpperNoiseBandwidthFrequency	Gets the frequency of the upper boundary of the noise bandwidth, in hertz. This specifies the highest frequency at which there is significant noise.
	UpperNoiseBandwidthLimit	Gets the offset from the center Frequency to the upper limit of the noise bandwidth, in hertz.

Methods

	Name	Description
	AddAndRemoveExistingDataT	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.
	AddData	Creates a new signal by adding data in addition to the data existing on this signal.
	AddNoiseTemperature	Creates a new signal by adding noise temperature (such as thermal noise), in kelvin.
	ApplyGain	Create a new signal by applying a gain to this signal. The gain is applied to both the signal Power and NoisePower.
	ContainsDataByType(Type)	Gets a value indicating whether this signal contains data of the specified type.
	ContainsDataByTypeT	Gets a value indicating whether this signal contains data of the specified type.
	CreateSignal(Double, Double, Double, Double)	Create a new noiseless signal based on the given properties. To modify a preexisting signal, use ModifySignalProperties(Double, Double, Double, Double, Double, Double, Double) or similar methods on the preexisting signal instance.
	CreateSignal(Double, Double, Double, Double, IEnumerableObject)	Create a new noiseless signal based on the given properties. To modify a preexisting signal, use ModifySignalProperties(Double, Double, Double, Double, Double, Double, Double) or similar methods on the preexisting signal instance.
	CreateSignal(Double, Double, Double, Double, Double, Double, Double)	Create a new signal based on the given properties. To modify a preexisting signal, use ModifySignalProperties(Double, Double, Double, Double, Double, Double, Double) or similar methods on the preexisting signal instance.
	CreateSignal(Double, Double, Double, Double, Double, Double, Double, IEnumerableObject)	Create a new signal based on the given properties. To modify a preexisting signal, use ModifySignalProperties(Double, Double, Double, Double, Double, Double, Double) or similar methods on the preexisting signal instance.
	Equals(Object)	Indicates whether another object is exactly equal to this instance. (Overrides ObjectEquals(Object).)
	Equals(Signal)	Indicates whether another instance of this type is exactly equal to this instance.
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetDataByType(Type)	Gets signal data based on the type of data requested. This data represents optional properties on the signal.
	GetDataByTypeT	Gets signal data based on the type of data requested. This data represents optional properties on the signal.
	GetDataList	Create a copy of the signal data. The Signal will not reflect changes to the list. This data represents optional properties on the signal.
	GetHashCode	Returns a hash code for this instance, which is suitable for use in hashing algorithms and data structures like a hash table. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
