bandwidth (Control Design and Simulation Module, MathScript Function)
Member of the frqrsp class.
Syntax
band = bandwidth(SysInSISO)
band = bandwidth(SysInSISO, magdrop)
Description
Calculates the bandwidth of a single-input single-output (SISO) system model. The bandwidth is the frequency, relative to the DC gain, at which the frequency response magnitude of the model drops below a threshold value you specify.
Inputs
| Name | Description |
| SysInSISO | Specifies a linear time-invariant (LTI) SISO model. SysInSISO is a model in transfer function, zero-pole-gain, or state-space form. |
| magdrop | Specifies the magnitude drop threshold, in decibels (dB). The default value is -3 dB. magdrop is a real scalar. |
Outputs
| Name | Description |
| band | Returns the bandwidth of the SysInSISO model. The bandwidth is the frequency, relative to the DC gain, at which the frequency response magnitude drops below the value of magdrop. band is a real scalar. |
Examples
SysInSISO = tf([1], [1, 1])magdrop = -2
band_2DB = bandwidth(SysInSISO, magdrop)
