Claims28
A method for controlling one or more parameters of an amplifier system comprising:
- receiving an indication of an estimated temperature associated with the amplifier system;
- determining one or more parameters of the amplifier system in response to the indication wherein:
- the one or more parameters comprise a selected frequency response of the amplifier system, such that the selected frequency response of the amplifier system varies as a function of the estimated temperature;
- and
- determining the one or more parameters of the amplifier system in response to the indication comprises selecting the selected frequency response corresponding to the estimated temperature from a plurality of stored frequency responses;
- and
- causing the amplifier system to operate in accordance with the one or more parameters.
A method for controlling one or more parameters of an amplifier system comprising:
- receiving an indication of an estimated impedance associated with the amplifier system;
- determining one or more parameters of the amplifier system in response to the indication;
- and
- causing the amplifier system to operate in accordance with the one or more parameters.
An apparatus for controlling one or more parameters of an amplifier system comprising:
- at least one input configured to receive an estimated temperature associated with the amplifier system;
- and
- a controller configured to:
- determine one or more parameters of the amplifier system in response to the indication, wherein the one or more parameters comprises a selected frequency response of the amplifier system, such that the selected frequency response of the amplifier system varies as a function of the estimated temperature, wherein determining the one or more parameters of the amplifier system in response to the indication comprises selecting the selected frequency response corresponding to the estimated temperature from a plurality of stored frequency responses;
- and
- cause the amplifier system to operate in accordance with the one or more parameters.
