Hello, I am an electrical engineering student currently working on analog filters, specifically cascaded Butterworth filter approximations, also known as Linkwitz-Riley filters. In my MATLAB code, I generate bandpass filters from individual high-pass and low-pass filters, which together form a c...

Yes, some readers might now argue that I used roughness in a crazy way in my last post, in my approach to finding a large twin prime pair. That is, I deliberately constructed a family of integers...

The model demonstrates the mathematical relationship between the input impedance and the output load for a buck converter.
How can we use roughness in an effective context to identify large primes? I can quickly think of quite a few examples where we might do so. Again, remember I will be looking for primes with not just...

Generative AI has become one of the most influential trends of recent years, powering tools like ChatGPT and Copilot that have transformed how we live and work. Beyond these domains, generative AI is also reshaping industries, and robotics is no exception. At MathWorks, we are excited to explore how...
In the world of Analog/Mixed-Signal Integrated Circuit (IC) design, transfer functions have long been the go-to method for representing and analyzing linear time-invariant (LTI) circuits. However, this traditional approach comes with its own set of limitations: Single-Input-Single-Output (SISO) Lim...
