Direct form refers to a specific way of implementing digital filters, characterized by its straightforward structure that directly relates the input and output signals. This implementation is crucial for both finite impulse response (FIR) and infinite impulse response (IIR) filters, as it allows for efficient calculation and ease of understanding. In direct form, the filter's coefficients are directly applied to the input signal, making it simpler to visualize and implement in hardware or software.
