Known as the superheterodyne circuit, this invention became a basic feature of VHF wave reception. Early commercial radio broadcasting impressed information on a carrier wave via amplitude modulation (AM), which varies the carrier wave’s power. AM signals can be sent long distances and are perfectly suited for simple broadcasts such as talking or unaccompanied singing. However, AM is not well-suited for complex broadcasts such as a symphonic performance, and it is easily disrupted by static from electrical storms and random electric interference from machines.
