  • Forum Post: Re: howto combo the FilterPro and Tina-TI

    Rick Downs - WEBENCH Design Center
    At the moment, the answer unfortunately is yes: you would have to draw the schematic by hand in TINA. We currently don't have a way to move designs from FilterPro to TINA easily. This is something we plan to address in a later release of FilterPro, but at the moment, adding that feature is unscheduled...

    Tony Canas
    Dear TI, I have been using Filter Pro (V3.1.05) to design sone low-pass active filters (with excellent results!). I noticed when looking in detail at teh Bode plots, that in each decade interval of frequency there are 11 vertical grid lines insetad of 10, and that the slightly larger axis...

    I agree with Thomas. This is a feature that has caused me to revert to v2 of FilterPro. Thanks Eric

  • Forum Post: FilterPro 2.0 vs 3.1 show different component values

    Scott George
    Made design at home using FP2 and FP3 at work to find very different component values for filter at output of RTD temp sensor. Filter is 1 Hz, 2 pole LPF, Gain = 1 (0 dB), MFB Single end, Butterworth, using E96 resistors/ E12 caps. FP3 Gain plot shows -30 dB in pass band though header shows G = 1. Can...

  • Forum Post: FilterPro 3: Gain < 1 not allowed?

    Ole J Gauteplass
    Hi, I just started using FilterPro 3 (3.1.0.23446) and I am surprised to see that I am not allowed to specify a gain less than 1. For an MFB filter this should be allowed. Since this is possible in FilterPro 2 it must be a bug in FilterPro 3? Br Ole

    Can someone post a link to the old one please? The new one needs to re-incorporate the old ones features and people need a stop-gap while this is being done. Thanks

    From the FilterPro 3 user guide : "Items in the schematic are either red or blue. Red Label: Items in red are not available for editing. These are labels identifying certain aspects of the schematic. Blue Label: Items in blue are available for editing. Change the component...

  • Forum Post: Designing a BP filter

    Frank QT
    Hi, I am trying to design a filter for my signal. Signal is as follows: 600nsec on, 400nsec off. (1MHz with 60% duty cycle). I like to suppress noise elsewhere and that is the primary purpose of the filter. Rise time is important for me so the filter should not reduce the rise time a lot. (target...

  • Forum Post: FilterPro Design Report

    Gerhard Kreuzer
    Hi, allmost all filters need more than one stage. I tried to design a filter usijg 2 stages and want to get out a nice design report. The schematic only shows the left part of the design, approximately 1.2 stages, the rest is off the paper. Is there any workaround to fix that and maybe this...

  • Forum Post: Re: Gain values reported wrong for high-pass MFB filters >2 poles

    Rick Downs - WEBENCH Design Center
    Harvey, Short of doing the math to find the transfer functions of each stage (which I'll leave to you), I built the circuit in TINA-TI, which you can download from http://www.ti.com/tina-ti. I've attached the TINA circuit: (Please visit the site to view this file) Using real op amps...

  • Forum Post: Incorrect Q value in HPF?

    matthew fortin
    In the FilterPro Desktop version, I am designing a 3rd order Chebyshev 0.5dB 135kHz High Pass Filter with a stopband freq of 10kHz. For the first stage, it lists a Q = 0.5. Doesn't Q=0.5 mean 2 repeated real poles at Fo? Is this mistake or is there a reasoning behind this? Shouldn't this stage...

    Hi Khang, thanks for replying. The project I'm interested in is a guitar speaker simulator, designed to reproduce the frequency response of a particular speaker/cabinet. Something like the image below. I can design the low pass and high pass filter using the Filter Designer software, but ideally...

    Patrick Shearer
    Thanks for the info, Khang! Do you know of any software that will let me design circuits to reproduce the peaks in between the high and low pass filters? Preferably something where I can type in the center frequency, change in sound pressure level (dB boost or cut) and Q and have it return the component...

  • Forum Post: FilterPro 3.1 gives wrong cutoff frequency designs for low-ripple Chebyshev lowpass filters

    Thomas Jackson
    I am designing low ripple (epsilon = 0.016 (0.001 dB)) 6-pole Chebyshev lowpass filters. The FilterPro 3.1 design results seem to have the cutoff frequency at the -3dB (0.707) point and not at the 1/(1+epsilon 2 ) point.
