What is continuous signal modulation?

Continuous-phase modulation (CPM) is a linear baseband modulation technique in which the message modulates the frequency of a continuous-phase signal. The signal has memory because the phase of the carrier is constrained to be continuous.

What is phase modulation technique?

Phase modulation (PM) is a modulation pattern for conditioning communication signals for transmission. It encodes a message signal as variations in the instantaneous phase of a carrier wave. Phase modulation is one of the two principal forms of angle modulation, together with frequency modulation.

How many types of continuous modulation are there?

There are two types of modulation. One type of modulation is used for continuous wave and second type of modulation is used for non-continuous wave. Amplitude modulation, frequency modulation, and phase modulation are used for continuous wave and sinusoidal waves.

Which signal is known as Cpfsk?

Continuous Phase Frequency Shift Keying (CPFSK) is a modulation that, as its name implies, can be characterized as a traditional frequency shift keyed (FSK) signal constrained to maintain continuous phase at its symbol time boundaries.
