Engineering Signal Analysis - Theory, is an introductory textbook on the analysis of signals in time and frequency. It takes an engineer’s perspective and discusses how to characterize, analyze and operate on signals. The basic theoretical concepts, Fourier series and transform, are explained in continuous time. It then introduces discrete-time signals, addressing how sampling and finite signal duration affect spectral analysis. It discusses the discrete Fourier transform and its use in spectral estimation. The book concludes with an introduction to linear systems and signal filtering.
This handbook guides students through concepts, content, and exercises that help them develop media literacy by understanding media and power. The authors want students to not only gain the ability to critically analyze the languages and discourses – textual, visual, audio, and code – that people use to create and interpret media content, but also to understand the overarching context: media possess immense power in contemporary societies around the world.
Semillas: Elementary Spanish II is an intermediate Spanish open-access textbook with reading, listening, speaking, and writing practice.

The textbook provides instructors and students with lessons, vocabulary lists, videos, PDFs, projects, and exercises.
Kevin J. Hinders’s The Design of the Built Environment offers an exploration of the architectural, cultural, and historical development of the University of Illinois Urbana-Champaign campus and its surrounding context. Structured around thematic walking tours, the manuscript examines architectural principles and then uses the campus and its surroundings to illustrate the concepts. It delves into the evolution of public spaces, technical design considerations, and the influence of local, regional, and national planning. Through case studies, historical analysis, and design theory, Hinders illustrates how built environments reflect collective values, cultural shifts, and functional needs. The work emphasizes experiential learning and encourages readers to engage with the built world through observation, reflection, and spatial understanding.

This book is an introduction to some influential theories in philosophy of art. It combines excerpts of historically important texts from European and American culture with explanations of the key ideas in those texts. The most recent of these texts dates from 1929.
Constitutional Law with a Twist: Less is More is designed for a one-semester survey course on federal constitutional law. The casebook covers the content of a typical four-credit survey course: the structure of the U.S. government and individual rights (other than First Amendment rights and rights unique to criminal law). What differentiates this casebook from most other constitutional law casebooks is that this book is deliberately short. It reflects the author’s philosophy that students often experience more joy, more depth, and more growth in an introductory course on constitutional law when there is less reading, more emphasis on contemporary cases, and more feedback on interim work. The book’s preface and the introduction to the accompanying teacher’s manual describe the book’s approach in detail to help faculty decide whether this casebook is a good fit for them and their students.
This OER textbook focuses on the foundations of entrepreneurship and starting a business. The text is divided from the theoretical underpinnings of the discipline; entrepreneurship traits and characteristics and the activities that precede starting a business.
Musics: Diversity, Difference, and Synergies is a radical re-imagining of how music can be studied. Non-Western, vernacular, and Western art music are valued equally and studied at the same level of depth. Of equal importance is the emphasis placed on hands-on doing. Scales common to Jazz and Western art music are learned by playing them on the piano. Rhythmic skills are embodied on the darbuka, a Middle Eastern goblet drum, through the study of Turkish rhythmic cycles called usuller. Pitch recognition is developed by singing paltas (pitch patterns) for Indian ragas and melodic studies for Turkish makamlar using fixed-do solmization systems. Training in moveable-do solfege for Western art music begins with conducting as a foundation. This is followed by the addition of takadimi syllables for rhythm, solfege syllables aligned with scale degrees, and, finally, pitch.
