Comb filtering when sampling frequency is not multiplicative of the interference fundamental frequency

 Hi all,

 
I would like to apply a notch comb filter (e.g. by using the iircomb function), but my sampling frequency is 976 Hz and the fundamental frequency of the noise signal is 50 Hz.
 
Any ideas of how I could achieve that would be greatly appreciated. An alternative would be to use multiple notch filters (e.g. iirnotch) but this would increase dramatically the associated computational costs.

You have to change the Sampling frequency such that you can get the sampling frequency to be a multiple of noise frequency.
 

You can do this my a combination of down-sampling and up-sampling. Find a fraction such that the sampling frequency is converted to ANY multiple of noise frequency. Not that it can be any multiple not necessarily 1000Hz.

Get MATLAB projects with source code for your learning and research. SIMULINK is a visual programing environment specially for time transient simulations and ordinary differential equations. Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model r...

USING MACHINE LEARNING CLASSIFICATION ALGORITHMS FOR DETECTING SPAM AND NON-SPAM EMAILS

    ABSTRACT We know the increasing volume of unwanted volume of emails as spam. As per statistical analysis 40% of all messages are spam which about 15.4 billion email for every day and that cost web clients about $355 million every year. Spammers to use a few dubious techniques to defeat the filtering strategies like utilizing irregular sender addresses or potentially add irregular characters to the start or the finish of the message subject line. A particular calculation is at that point used to take in the order rules from these email messages. Machine learning has been contemplated and there are loads of calculations can be used in email filtering. To classify these mails as spam and non-spam mails implementation of machine learning algorithm  such as KNN, SVM, Bayesian classification  and ANN  to develop better filtering tool.   Contents ABSTRACT 2 1. INTRODUCTION 4 1.1 Objective : 5 2. Literature Review 5 2.1. Existing Machine learning techniqu...
