QPSK modulation is the process of digital modulation which based on the phase changes to represent data bits of information. Addressing to the need of enhancement implementation of transmitter design, ...

The figure below shows a block diagram of a table-top AM radio from the late 40’s where the radio tunes in stations at the frequency frf = frequency of OSC1 – 455 kHz.

The type of modulation used is suppressed-carrier amplitude modulation. Because the subcarrier is suppressed, only the sidebands are obtained at the output of the modulators. This results in complete ...

This paper designs a frequency modulation (FM) transmitter for wireless communication systems, focusing on the design and implementation of the carrier oscillator circuit, high-frequency power ...
