LC78834M Operation
1. Digital Filters
The LC78834M performs the following processing.
Oversampling
Two 2
×
interpolation filters (constructed as FIR filters) are cascade connected.
Two FIR filter stages, a 43rd order and an eleventh order, are cascade connected to perform 4
×
oversampling.
De-emphasis
A first-order IIR filter is used for digital de-emphasis.
The filter coefficients are set up to correspond to the sampling frequency fs, which may be 32, 44.1, or 48 kHz.
See page 11 for the filter characteristics when de-emphasis is on.
— De-emphasis on/off
De-emphasis on: EMP pin = high
De-emphasis off: EMP pin = low
— Filter coefficient selection
No. 4838-6/14
