Abstract: | Once a circuit is decided upon, detailed analysis of the circuit responses and detailed calculations of the effects of component variations must be made. The analyses may show unacceptable responses or unacceptable behavior of the circuit. Further modifications of the trial circuit may have to be made and a detailed re-analysis may be necessary. Occasionally, the conceptual circuit may have to be replaced and a different circuit may be called for. In this latter case, the conceptual design steps must be repeated. |
