voice frequency उदाहरण वाक्य

Sending a sound vibration to an eardrum or making a voice frequency currents flow in phone wires or sending a telegraph message or affecting a computer circuit would require a transfer of energy, which would seem to violate the conservation of mass and energy in the universe both at the present and in the past.
Since the objective is to provide DSL to locations where no other data service can reach, or is needed ( e . g . onto a farm ), and ordinary telephone service is very immune to cross talk from ADSL due to ADSL not using voice frequency range, the cross talk issue is further reduced.
