Bandpass filter with integrated variable gain function using improved resistor array
摘要:
The invention enables a gain adjustment in a receiver to improve signal quality by varying resistance of an input resistor array of a bandpass filter, the array having a plurality of resistors in series with switches that out of the path of the current when the resistors are in use.
