Tín hiệu rời rạc (discrete-time signal) chỉ được xác định tại một số thời điểm nào đó. Khoảng cách giữa các thời điểm này không nhất thiết phải bằng nhau, nhưng trong thực tế thường là lấy bằng nhau để dễ tính toán. Có thể tạo ra tín hiệu rời rạc từ tín hiệu liên tục bằng 2 cách. Một là lấy mẫu tín hiệu liên tục, hai là đo hay đếm một đại lượng vật lý nào đó theo một chu kỳ nhất định, ví dụ cân em bé hàng tháng, đo áp suất không khí theo giờ......

DISCRETE-SIGNAL ANALYSIS AND DESIGN- P37:Electronic circuit analysis and design projects often involve time-domain and frequency-domain characteristics that are difÞcult to work with using the traditional and laborious mathematical pencil-and-paper methods of former eras. This is especially true of certain nonlinear circuits and sys- tems that engineering students and experimenters may not yet be com- fortable with.
