Abstract
A sampling rate converter has a pulse-dulation modulator for converting a pulse-code-modulated signal, which has been sampled with a first sampling frequency, into a pulse-dulation-modulated signal, and a counter for counting pulses of the pulse-dulation-modulated signal and producing a count in each sampling period determined by a second sampling frequency. The sampling rate converter also includes a multiplier connected to the output of the counter.
Claims4
A sampling rate converter comprising:
- a pulse-density modulator for converting a pulse-code-modulated signal, which has been sampled with a first sampling frequency, into a pulse-density-modulated signal;
- a counter for counting pulses of said pulse-density-modulated signal and producing a count at each sampling period determined by a second sampling frequency;
- said pulse-density-modulator comprising adder means, and comparator means having an input connected to an output of said adder means, and a one-sample delay unit having an input connected to an output of said adder unit, and an output of said one-sample delay unit being connected to a second input of said adder means.
A sampling rate converter comprising:
- a pulse-density-modulator for converting a pulse-code-modulated signal, which has been sampled with a first sampling frequency, into a pulse-density-modulated signal;
- and
- a counter for counting pulses of said pulse-density-modulated signal and producing a count in each sampling period determined by a second sampling frequency;
- said pulse-density-modulator producing pulses in the form of a single bit pulse-density-modulated signal, and said counter accumulating said single bit pulse-density-modulated pulses during each cycle of said second sampling frequency.
