Quantization noise in filter bank analog-to-digital converters

Analog-to-digital converters (ADCs) making use of analog and digital filter banks have been proposed as a means to increase the performance of the analog-to-digital conversion. In this paper we consider the quantization noise in such filter banks. Basically, two different schemes are treated, namely single-rate and multirate filter bank ADCs. Further, both narrow-band and wide-band input signals are considered, The differences between these two ADC schemes and the single conventional ADC are pointed out.
