Classification: CPC H  G | IPC G  H

Claim 0:
1. A composite analog-to-digital converter (ADC), comprising:
a low resolution ADC configured to receive and digitize analog data, the low resolution ADC having a low resolution and a high operating speed;
one or more high resolution ADCs configured to receive and digitize the analog data, the one or more high resolution ADCs having a resolution higher than the low resolution ADC, and an operating speed lower than the high operating speed of the low resolution ADC;
a sample clock generator to provide a sample clock signal to the low resolution ADC and to a clock divider;
a mixer to receive the analog data and connected to at least one of the one or more high resolution ADCs; and
a local oscillator connected to the mixer to allow at least one of the one or more high resolution ADCs to be tuned to sample a portion of a spectrum of the low resolution ADC.
