WebJan 25, 2024 · Frame blocking or framing is a fundamental signal processing technique that consists of dividing the original signal into # F blocks often called frames with length N f an overlap M and a framing hop H ( H = N f − M) . Overlapping the frames help avoiding information loss in between adjacent frames. Figure 16: Framing # WebPadding is something that you need when you are putting a variable-length data in a fixed-length blocks.
