Speech, music, seismic vibrations, oil prices, and climate measurements are all examples of stochastic (random) signals. In this textbook—intended for individuals with prior training in introductory signal processing and introductory probability theory—we develop techniques to process such signals to extract useful information. We present case studies ranging from music to photographic images to oil prices to climate data to the motion of individual biomolecules. This textbook, as an interactive textbook ("iBook"), makes use of your device's ability to display dynamic information through films and animations and to hear the results of the techniques applied to music. At the end of every chapter there are homework problems ranging from easy to "olympic". We make use of your device's interactive capabilities to offer 59 laboratory experiments in signal processing. The experiments use the camera, the microphone, the speakers, and the graphical user interface. These experiments are not simulations; they are examples of real digital processing of signals in your device. In this time of at-home and online learning, this is the way to learn signal processing through study and experimentation.

"Base to Base Converter" converts both integer and fractional numbers to and from all bases between 2(binary) and 16(hexadecimal). Together with performing calculations, it explains the steps in detail. Conversion from base A to base B is done and explained in two stages: 1. Base A to base 10(decimal), 2. Base 10(decimal), to base B. Every effort was made to minimize numerical error when converting fractional numbers. Also available: Direct conversion with explanation of steps: * From base 2(binary) to 4, 8(octal), 16(hexadecimal); * From base 3 to base 9; * From base 4 to base 16(hexadecimal). We welcome suggestions, our e-mail is graphmath@aol.com.

Verdict

The call

The clearest difference is rating: Base to Base Converter at 5.0 against Stochastic Signal Processing's 4.7. Stochastic Signal Processing's advantage is review sentiment (67% vs 50%) and ratings volume (6 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

Base to Base Converter holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Stochastic Signal Processing has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 67% of Stochastic Signal Processing's written reviews are positive against 50% of Base to Base Converter's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 5 weeks. Both last shipped on October 24, 2026.
