![]() ![]() ![]() As shown below, the user can set the tolerance value for the components, 1%, 5%, etc. As a consequence, the program only uses standard industry component values for the R’s and C’s. This program was written by an experienced engineer. Having said this, you need to look at the Adjustable Gauss Polynomial which is incorporated into this program. If you are somewhat experienced with analog filter design, then you understand the importance of selecting the appropriate design polynomial for the filter. The program synthesizes filters from the Butterworth, Chebyshev, Gauss, Bessel, Papoulis, and Adjustable Gauss Polynomials. This free op amp filter design program synthesizes both VCVS and MFB low pass, high pass, notch, band pass, and all pass filters. © 1994-2022, Microstar Laboratories, Inc.Download Iowa Hills OpAmp Filter Designer software. Return to the Software page or iDSC 1816 page. Microstar Laboratories supports a limited set of commercial Linux distributions. Or you may contact us and ask for the software. You may download a copy of the DAPtools Basic CD this includes all of our user manuals and the DSCview for Linux software. You may obtain a copy of DSCview for Linux in one of two ways. The user may have any number of graph, table and disk log screens. There are three types of output data screens: graph, table, and disk log. Paste - pastes the copied iDSC configuration from the clipboard to another iDSC.Copy - copies the entire iDSC configuration from the iDSC to the clipboard.Remote Master - configures a Master iDSC board as a remote master.Raw Data - selects raw data rather than filtered data from the iDSC.External Board Enable - enables the external board.External Board Calibrate - calibrates the external board if the external board is enabled.Mode - the mode of the iDSC board: Independent, Slave of Xxx (where Xxx is the name of the iDSC board) or Master (automatically set when the slaves are selected).DSCs - the number of iDSC boards in the system.The user can enter the following parameters: Support for multiple iDSC boards is activated through the Group Interface, selected through the DSCview menu, System|Board Setup Display. Paste - pastes the copied filter design parameters from the clipboard to another filter design. ![]() Copy - copies the filter design parameters from the filter design to the clipboard.Defaults Load - loads the default filter response graphs for a particular sample rate.Y Display - displays the filter's amplitude response in linear, linear zoom, log, log zoom, or unit step form.Crosshair Track - tracks the filter response curve to determine the exact cutoff frequency, cutoff slope, or attenuation at a particular point.In addition, the user can access these additional parameters through the right mouse button: Attenuation - the response in the stop band, expressed as a value, in the range 6.0 to 12.0.High Cutoff Slope - the width of the second transition band, expressed as a % of the Nyquist frequency, in the range 0 to 80.High Cutoff Frequency - the second transition band, expressed in Hertz, in the range 2% to 80% of the Nyquist frequency.Low Cutoff Slope - the width of the first transition band, expressed as a % of the Nyquist frequency, in the range 0 to 80.Low Cutoff Frequency - the first transition band, expressed in Hertz, in the range 2% to 80% of the Nyquist frequency.Sharpness - the number of taps in the final filter stage, an odd number in the range 37 to 255 (range dependent on sample rate) that determines the sharpness of the corner frequency response.Filter Type - the filter type, lowpass or bandpass.Filter Name - a unique name for each filter design.Selecting a tab puts that screen on top in the window. There are eight tabs that the user can name to identify up to eight different filter designs: a different filter design for each channel, if required. When the Filter Design tab is selected, it activates the Filter Design Screen. IDSC filters are activated through the Configuration Window, which has a Filter Design tab to display the Filter Design Screen and an Input tab to display the Input Screen. All user interfaces share a common look and feel to designing and configuring filters. So customers can, if they wish, program their own user interfaces to replace DSCview. Microstar Laboratories includes appropriate software from DSCview in its support for development environments that include Kylix and GNU C++. DSCview requires no programming, and provides a graphical interface to DSCview, a complete Linux application, allows immediate and easy access to the iDSC 1816. ![]()
