Abstract
The present technique pertains to a signal processing apparatus, a signal processing method, and a receiving apparatus that enable gain control to be appropriately performed on various interfering signals. An amplifier controls a gain according to a count value to amplify a signal, and a comparator compares the signal outputted by the amplifier with the count value. An accumulator counts the count value according to an output from the comparator. The present technique can be applied to, for example, a receiving apparatus that receives an RF signal for a television broadcast.
Claims16
A signal processing apparatus comprising:
- an amplifier that controls a gain according to a count value to amplify a signal;
- a comparator that compares the signal outputted by the amplifier with the count value;
- and
- an accumulator that counts the count value according to an output from the comparator.
A signal processing method comprising:
- controlling, by an amplifier, a gain according to a count value to amplify a signal;
- comparing, by a comparator, the signal outputted by the amplifier with the count value;
- and
- counting, by an accumulator, the count value according to an output from the comparator.
A receiving apparatus comprising:
- an amplifier that controls a gain according to a count value to amplify a signal;
- a comparator that compares the signal outputted by the amplifier with the count value;
- an accumulator that counts the count value according to an output from the comparator;
- and
- a demodulation circuit that demodulates the signal outputted by the amplifier.
