Dear all, I have a question regarding the usage of single_pole_iir_ff filter in the fftsink_nongl.py which is used to construct the spectrum analyzer in gnuradio-3.1.3. what is the usage of this iir filter since the alfa value is equal to 1 which give the value of input the same as the value of the output (refering to the single pole iir filter explanation in https://radioware.nd.edu/documentation/a-dictionary-of-the-gnu-radio-blocks -- please fixme if i am wrong). in the previous post, firas told that this filter is used for the averaging purposes (http://old.nabble.com/question-regarding-usrp_fft.py-td24440532.html#a24466469) but what is the value that it average?
