## How to test a filter functionality

Just use ADS for quick design: pass band=400Hz, stop=450Hz, ripple inband=3dB, attenua stop=60dB, then max flat needs 45 orders. elliptic needs 8 orders, some 7mH inductor what is your purpose for this filter?

## Bandstop Elliptic Analog Filter Design

Yes i searched for it but still dont know how to design it from transfer function. Is the 3rd order good approximation for this problem? and is my solutions correct for the relevant problems? Just to avoid misunderstandings: The program you have used (filter Solutions from NuHertz) uses a somewhat uncommon met

## Pseudo Elliptic Filter Design

hi every one. first of all,sorry about my english:-D. i want to create a code for synthesizing pseudo elliptic filter to achieve to the circuit of a low pass filter,i read some article but i just confused.please help me. i need to solve this problem seriously, so please help me with a simple example and procedure. (...)

## Filter design using Defected Ground Structures and Defected Micro-strip Structures.

Hi, I am trying to use DGS and DMS to design elliptic filters on micro-strip line. But, it is giving a lot of problems like mutual coupling between two DGS, the impedance and S-parameter characteristics change when DGS is shifted on a microstrip line et al.. This is not enabling me to make a proper design of the (...)

## SSB Weaver method filtering

Here the most important specification of the filter is hih sideband rejection.Therefore elliptic filters are more convenient.

## FPGA filter coefficients

Hey guys, It is my first time here and my first time working with SW filters or oversampling filters. In fact my problem is the following one. I have designed a filter using the Fdatool that you can find in matlab. 250 kHz sampling freuqency some attenuation 5 kHz cut off elliptic and (...)

## Filtroid OS DOS 3.2. - software for filter circuits

FILTROID OS DOS 3.2 Description: FILTROID, a program that synthesizes, edits, analyzes, and joins filter circuits from audio to microwave frequencies. FILTROID is capable of designing from many different transfer functions, including Butterworth, Tchebychev, elliptic, and Pole Placed. In addition, the user can input G or (...)

## what do you mean by first order, second order and third order filters?

Order of filter is defined by number of active elements in the filter. 1. I guess, you mean reactive elements 2. It's not generally, true, only for some of the simple filter prototypes you mentioned. A 3rd order Chebyshev II or elliptic low-pass has more reactive elements. Strictly spoken, filter order (...)

## About Elliptic Bandpass Filter Design

hi everyone: i have got an assignment about designing an elliptic bandpass filter, we dont have to build the actual circuit, all i need is: do the calculation, put the values in the simulating software to get the graph and a report. and the task is: "To design an elliptic (...)

## gain rise in stopband duo to nonideal opamp

Hi,guys.I use Thomas II biaquad structure to realise a 6th order elliptic low pass filter,but there is a gain peak in stopband shown in the picture posted.I try to get some analytical expression of the transfer function considering the nonideal model of opamp but failed to come to a reasonable and practical result. The only (...)

## What is the order equation and pole zero equation of elliptic filter in DSP.

Hi........... Nice to meet u ALL. I want to know about the order equation and pole-zero equation of active elliptic filter but I can't find it. After that, I can write this equation in MATLAB and leacture note. It is very useful for my thesis. Please, can anybody help me ? Thanks for everythings,

## question on gm-c filter

Hi, all, In following figure is an elliptic prototype filter, I'd like to transform it to gm-c counterpart, for example, I could transfer the source and load resistors to 1/gm, but as to the inductors and capacitors, how to simulate them with gm units? or could anyone recommend some documents on it? Thanks in (...)

## How to convert design with capacitors/inductors to one with transistors in ADS ?

Hi I have design a standard elliptic filter in ADS by capacitors and inductors. is there any option in ADS to convert my design to a design with transistors? thanks

## quantization of internal data bus of digital filter

I want to quantize internal data bus of an elliptic filter in SIMULINK MATLAB. I used FDA tool for that purpose. but I don't know where I must use rounding and saturate blocks. Please help me!

## Can anyone tell how to design elliptic filter

Hello friends... Can you help me in designing an elliptic filter. I'm planning to do a switched capacitor elliptic Ladder filter for an order 5. I had uploaded the passive structure and the corresponding signal flow graph. Thanks in Advance Bhagath Added after 58 minutes: u

## Mapping coefficient of continues transfer function to discre

Hi, I have a similar problem where I want to "map" an analog filter to a digital filter where both the phase and amplitude responses of the analog filter should be preserved (in the digital filter). In essence I want a digital "representation" of an analog filter. For certain analog (...)

## Designing a bandpass elliptic filter

Sec, Go here for a Master's thesis about elliptic filter design that I posted before. /Hunter

## Need a suitable software for simulate microstrip filter

Hi I am a student of telecommunication and working on a project in university. I designed a Quasi-elliptic filter with microstrip line. I want to simulate it now. I simulated my design with HFSS, but it is very slow. EM simulator of AWR ( Microwave Office) is slow too for my structure and i cant optimize it. Schematic (...)

## Optimum Return Loss [hlp]

Hi From the band pass to the next stage, it should be zero, since ideally you want the energy totally transferred within the band of interest. cheers Sal No One: Is depend of type of used filter ie. Bessel, Buttewort, Chebyschev, Cauer (elliptic). Ideal filter without resistive loss (...)
