At least one amplifier is selected from a first bank of non-linear amplifiers. At least one amplifier is selected from a second bank of non-linear amplifiers. The number of amplifiers selected from the first and second banks remains constant. Using the selected amplifiers, first and second components of a digital symbol are amplified using the first and second banks, respectively. The outputs produced by first and second banks are combined to produce an analog representation of the digital symbol.
