Digital Spectral Analysis: Second EditionDigital Spectral Analysis offers a broad perspective of spectral estimation techniques and their implementation. Coverage includes spectral estimation of discrete time or discrete space sequences derived by sampling continuous time or continuous space signals. The treatment emphasizes the behavior of each spectral estimator for short data records and provides over 40 techniques described and available as implemented MATLAB functions. In addition to
Digital Spectral Analysis offers a broad perspective of spectral estimation techniques and their implementation. Coverage includes spectral estimation of discrete-time or discrete-space sequences derived by sampling continuous-time or continuous-space signals. The treatment emphasizes the behavior of each spectral estimator for short data records and provides over 40 techniques described and available as implemented MATLAB functions.In addition to summarizing classical spectral estimation, this text provides theoretical background and review material in linear systems, Fourier transforms, matrix algebra, random processes, and statistics. Topics include Prony's method, parametric methods, the minimum variance method, eigenanalysis-based estimators, multichannel methods, and two-dimensional methods. Suitable for advanced undergraduates and graduate students of electrical engineering -- and for scientific use in the signal processing application community outside of universities -- the treatment's prerequisites include some knowledge of discrete-time linear system and transform theory, introductory probability and statistics, and linear algebra. 1987 edition.

Too big, gets hot on bottom
Color: Black
After receiving this, I see it's frequently returned. I wish I didn't buy it. It's too large for my space where I kept my previous warmer and I tried it out; it got quite hot on the bottom. Nothing great about it. I'm boxing it back up and back to the drawing board.

Great
Color: Silver
This coffee and tea warmer is an absolute game-changer! I work from home and love keeping my beverages hot throughout the day. This device truly lives up to its promises. It heats up incredibly quickly and maintains a consistent temperature, keeping my drinks warm for the price. I can’t find a better option, and the auto-shut-off feature is a huge plus. The temperature control is precise, and it actually performs as advertised. I highly recommend this product for its affordability, multiple temperature settings, and reliable performance. It has everything I was looking for in a coffee and tea warmer. The previous one I had worked well and had an auto-shut-off, but I kept accidentally shaking the cup, causing it to spill and melt. This one seems to be well-constructed and definitely worth the investment.

No more cold coffee!
Color: Silver
Great price for all the nifty features - timer, auto shut-off, hot and hotter! Large button icons and digital temperature display are easy to see. My coffee and tea stay hot enough to drink without making multiple trips to the microwave because I got busy and let it get cold. New best friend!

i can’t believe how long i went without this
Color: Silver, Color: Silver
i never expected how much of a difference this item would or could make in my nightly tea routine.
i’m a slow sipper and would normally have to get up and microwave my mug 1-2 times depending on how willing i was to stop everything i was doing and move out of my comfy spot to remedy the impending sad lukewarm experience. YALL! the temperature really does make it taste better (i already knew that) but now i can settle into my spot in cozy PEACE and take as long as i want to to enjoy my tea.
i was worried if the lower price point compared to other options on amazon would mean it may be lacking in quality or function, but NOPE! just a genuinely good deal (about $10 at the time of this review) and the features are all there. yes yes yes, go ahead and treat yourself because this one is worth it.
