Hartley’s Amplitude, Balanced and Single Band Modulations

Radioelectronics and Communications Systems, 2022
A new kind of modulation has been developed representing Hartley’s amplitude modulation (HAM) that differs from the amplitude modulation (AM) by the presence of two orthogonal components of amplitude-modulated signal making it possible to increase the HAM efficiency to 90% as compared to 33% for conventional AM at the maximum value of modulation index ...

Hartley Angular Modulation

Radioelectronics and Communications Systems
Hartley angular modulation (HAM) differs from the known angular modulation (AM) by the presence of an additional orthogonal (quadrature) component, which allows us to form the HAM signal as a sum of sine and cosine signals of the same frequency with the ...
