We develop optimal finite-sample approximations for the band pass filter. These approximations include one-sided filters that can be used in real time. Optimal approximations depend upon the details ...

When it comes to communication systems, differential circuits can always provide better performance over single-ended circuits. They can provide higher linearity, immunity to common mode interference ...

[Ryan] wanted a spectrum analyzer for his audio equipment. Rather than grab a micro, he did it the analog way. [Ryan] designed a 10 band audio spectrum analyzer. This means that he needs 10 band-pass ...

Today we are going to explain about one more important concept – “FILTERS”. An electrical filter is a circuit, designed to reject all unwanted frequency components of an electrical signal and allows ...

Can you buy a working radar module for $12? As it turns out, you can. But can you make it output useful information? According to [Mathieu], the answer is also yes, but only if you ignore the ...
