Description of 7project The general purnose of this group is to design a high-speed elect-onic equivalent of tne recht-nical dafferen ial analyzer A machine of the analog type is envisaged %hich will have sufficient flexibility and accuracy for most engineering problems Investigation to date have revealed the existerce of circuits which will adequately add subtract integrate and differentiate Multiplication presents a mo-e difficult problem It is accomplished on the mechanical dif*erential analyser by "integration by parts" This is not possible electronically since the variable of integration is limited to time alone For this reason emphasis at present is centered upon an investigation of all the circuits which have been used for multiplication, and the design of one which will be rapid accurate reliable and of sufficient range for use in a differential analyser
