Specifications were defined throughout the process, both to guide the design and to evaluate the actual performance of the completed design. Common amplifier specifications listed on commercial designs include those shown in Table 1, including more which do not apply, are difficult to set a target for, or are not easily testable. Target values were defined based on typical values and on what was a reasonable goal for this project. The specifications and their values are listed in the table below.
