DFD Plot Narrowband Freq Response VI

	# freq bins specifies the number of frequency bins between 0 and fs that this VI plots in the frequency response. The default is –1, which specifies that this VI automatically determines the number of frequency bins.
	narrowband filter in specifies the input narrowband filter. multirate filters contains the multirate filters this VI uses to construct the narrowband filter. filter type contains the type of filter. 0 Lowpass (default) 1 Highpass 2 Bandpass 3 Bandstop 4 Wideband-Lowpass 5 Wideband-Highpass
	phase view specifies the phase response display settings. unwrap? specifies whether this VI unwraps the phase. The default is FALSE, which specifies that the phase remains wrapped and is limited to [0, 2π). degree? specifies whether the phase appears in degrees or radians. The default is FALSE, which specifies that the phase appears in radians.
	dB on? specifies whether this VI uses decibels or a linear scale to express the magnitude response. The default is TRUE, which specifies that this VI converts linear magnitude response to decibels.
	error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. This VI or function runs normally only if no error occurred before this VI or function runs. If an error occurs while this VI or function runs, it runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node. status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. code is the error or warning code. The default is 0. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source specifies the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning. The default is an empty string.
	fs specifies the sampling frequency in hertz. The default is –1, which specifies that this VI uses the sampling frequency of the input filter.
	narrowband filter out returns a duplicate filter of narrowband filter in. multirate filters contains the multirate filters this VI uses to construct the narrowband filter. filter type contains the type of filter. 0 Lowpass (default) 1 Highpass 2 Bandpass 3 Bandstop 4 Wideband-Lowpass 5 Wideband-Highpass
	magnitude response returns the magnitude response of the filter.
	phase response returns the phase response of the filter.
	error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error. status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred. code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code. source describes the origin of the error or warning and is, in most cases, the name of the VI or function that produced the error or warning.
