WebQPSK is a modulation scheme that allows one symbol to transfer two bits of data. There are four possible two-bit numbers (00, 01, 10, 11), and consequently we need four phase … WebThe first three sections of the schematic are the modulation circuit. We first modulate the carrier wave, then amplify it. The AD654 changes the frequency of the output based on the voltage level of the input. The timing resistors and capacitors give a base frequency value for the IC to work with based on the equation found in the datasheet.

WebBinary phase-shift keying (BPSK), also known as bi-phase modulation, is a simple, popular digital modulation scheme. The symbol constellations are as far apart as possible, which is desirable for weak signal work. BPSK is also popular for its relatively simple spectrum-spreading capability. fourth payroll stonegate
