Operating Description
1. Digital Filters
The LC78836M performs the following calculations.
Oversampling
The oversampling circuit consists of 2
× interpolation filters (implemented as FIR filters) connected in series.
In standard-speed operation, the circuit implements 8
× oversampling by connecting three stages of FIR filters
(33rd,13th, and ninth orders) in series. In double speed operation, the circuit implements 4
× oversampling by
connecting two stages of FIR filters (33rd and ninth orders) in series. See page 9 for the filter characteristics.
De-emphasis
The LC78836M implements digital de-emphasis with a first-order IIR filter. The filter coefficients correspond to
sampling frequencies (fs) of 32, 44.1, and 48 kHz. (The frequencies are doubled in double-speed operation.)
See page 10 for the filter characteristics when de-emphasis is on.
— De-emphasis on/off switching
De-emphasis on: EMP = high
De-emphasis off: EMP = low
— Filter coefficient selection
