发明名称 RECEIVER WITH VARIABLE PREDETECTION BANDWIDTH BASED ON EXPECTED DATA RATE
摘要 This invention relates to selective call receivers (11), such as paging receivers, for receiving modulated data signals having a variable bit rate. A band pass filter (26), particularly an I. F. filter, is provided having an adjustable bandwidth. The bandwidth of the filter is adjusted in accordance with a code in the received signal which indicates the bit rate.
