A Comprehensive Exploration of Voice Telecommunications, Standards,and Analog Modulation TechniquesWeek 1 DQsDQ 1Do some researchon thehistory of the telephone, telephony, and voicetelecommunications.The ERR this week have some interesting articles....There have been a number of significant technological changes to the telephone servicesince the invention by Bell. The technology and service has evolved drastically in 100years. Besides the actual invention of the telephone, describe one significant technicalinnovation in voice telephony prior to 1975.Detail thereasonsfor your choice.Whyis your choice significant?What did itcontributeto the industry and/or subscribers?This DQ is about regular two-way, home-phone-typeVOICEtelecommunications in the UnitedStates; Plain Old Telephone Service (POTS).
