This may be used to set the amplitude of the cosine, either by using the sliding bar or typing a value in the text field. Its maximum and minimum values are determined by the GUI.
This may be used to set the frequency of the cosine as a multiple of 2*pi, either by using the sliding bar or typing a value in the text field. Its maximum and minimum values are determined by the GUI.
This may be used to set the phase of the cosine, either by using the sliding bar or typing a value in the text field. Its maximum and minimum values are determined by the GUI.
This may be used to set the DC level of the cosine, either by using the sliding bar or by typing a value in the text field. Its maximum and minimum values are determined by the GUI.
Use the pop-up menu to choose a filter from among the following choices:
Each filter, with the exception of the first difference filter, will have customizable parameters that can be specified in the Filter Specifications box at the bottom-right hand corner of the GUI. For many filters the option exists of using either a text field to type in the parameter or a sliding bar to set it. If the text field is used, the GUI will automatically limit the value to a maximum or minimum determined by the GUI if the value entered is not within the allowed range.
[b1,b2,b3,...,bn]/m
This plot displays the input sinusoid according to the parameters specified by the user. It updates itself immediately upon any change in the parameters.
This plot displays the output sinusoid according to the input signal and frequency response of the filter. It updates itself immediately upon any change in the input signal's parameters or the frequency response parameters of the filter.
This plot displays the amplitude of the frequency response of the filter selected by the user. It updates itself immediately to reflect any change in filter type or parameters.
This plot displays the phase of the frequency response of the filter selected by the user. It updates itself immediately to reflect any change in filter type or parameters.
Pressing this button will display the mathematical output of the filter system based on the sinusoidal signal parameters specified for the input as well as the frequency response. The result will appear immediately above the OUTPUT SIGNAL plot. Changing the current parameters will erase the result and the button must be pressed again to display the new output signal.
This menu item enables adjustment of the unit impulse and plotting line widths. Use the sliding bar to change the current line width; the above preview box will update to show the currently selected width. Pressing OK will close the window and apply the new line width to the GUI. This option may enable you to see high-frequency input signals more clearly.
