Stochastic Signal Processing vs BitSquare

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.

BitSquare is a mobile app-based platform designed to connect BitSquarers (BitSqrs) with their customers and followers. BitSqrs are individuals who seek to generate income through utilizing their skills and knowledge. They usually consist of professionals offering standalone and on-demand sessions, not necessarily engaged in creating ongoing content like creators do. Anyone can become a BitSqr and examples include consultants, technicians, therapists, coaches, trainers, tutors, among others.
