And Lyons' claim that zero-valued samples create new frequencies (replications) is incorrect (see 2nd graph). Another Lyons error is in https://www.embedded.com/dsp-tricks-building-a-practical-spectrum-analyzer/, where he confuses the WOLA algorithm with over-lap convolution. undo

• curprev 22:0622:06, 24 August 2022‎ Em3rgent0rdr talk contribs‎ 12,060 bytes −25‎ →‎Interpolation filter design: The problem with the original wording "inserting 2 zeros between each pair of real samples" is that the term "each pair" can easily interpreted in a non-intended way if the reader works under the assumption that a sample belongs to only one pair of samples. But really should say that the zeros are inserted between *all* original low-rate samples. undo Tag: Visual edit
