摘要: Publisher Summary The direct-form structure, which is the simplest form of digital filter structures, generates large roundoff noise for transfer functions having sharp frequency response behaviors and often supports limit cycles. Therefore, several other structures that have much better behavior in a quantized environment are employed. This chapter presents most important these structures. It focuses on binary arithmetic quantization sequences, along with statistical properties, propagation filters. describes scaling dynamic range considerations. discusses signal-to-noise ratio (SNR) performance simple class low-noise second-order based error-spectrum shaping (ESS), concept SNR to arbitrary also cascade-form implementations noise-reduction strategies such state-space design closed-form expressions certain minimum-noise
