WIRELESS CHARGER USING FREQUENCY ALIASING FSK DEMODULATION |
| 摘要 |
A frequency shift keying (FSK) demodulation component having of a sampler that receives an FSK modulated signal, samples the received FSK modulated signal, and outputs the sampled signal. The FSK demodulation component further includes a low pass filter that filters the sampled signal, and a frequency shift detector that detects shifts in frequency of the low pass filtered sampled signal. The FSK demodulation component then outputs an indication of the detection of shifts in frequency of the low pass filtered sampled signal. |

1. A frequency shift keying (FSK) demodulator, comprising:
a sampler that receives an FSK modulated signal, samples the received FSK modulated signal, and outputs the sampled signal; a filter that low pass filters the sampled signal output by the sampler; and a frequency shift detector that detects shifts in frequency of the low pass filtered sampled signal, and outputs an indication of the detection of shifts in frequency of the low pass filtered sampled signal. |
