Time-adaptive RF hybrid filter structures

A method of digitally controlling an analog filter device, the method comprising:

• using digital signals, controlling one or more digitally controlled analog signal amplifiers, wherein the digitally controlled analog signal amplifiers are configured to have a gain of the digitally controlled analog signal amplifiers controlled by the digital signals;
• using one or more analog time delay circuits coupled to signal input nodes of the digitally controlled analog signal amplifiers, causing one or more delays of signals input into the digitally controlled analog signal amplifiers;
• wherein at least a portion of the digital signals are as a result of a digital closed loop control circuit coupled to the digitally controlled analog signal amplifiers digitally controlling the gain of the digitally controlled analog signal amplifiers;
• and
• using a slope equalizer in the filter device to compensate for the slope of the filter device.

A system for digitally controlling an analog filter device, the system comprising:

• one or more processors;
• and
• one or more computer-readable media having stored thereon instructions that are executable by the one or more processors to configure the computer system to digitally control an analog filter device, including instructions that are executable to configure the computer system to perform at least the following:
• using digital signals, controlling one or more digitally controlled analog signal amplifiers, wherein the digitally controlled analog signal amplifiers are configured to have a gain of the digitally controlled analog signal amplifiers controlled by the digital signals;
• using one or more analog time delay circuits coupled to signal input nodes of the digitally controlled analog signal amplifiers, causing one or more delays of signals input into the digitally controlled analog signal amplifiers;
• wherein at least a portion of the digital signals are as a result of a digital closed loop control circuit coupled to the digitally controlled analog signal amplifiers digitally controlling the gain of the digitally controlled analog signal amplifiers;
• and
• using a slope equalizer in the filter device to compensate for the slope of the filter device.
