types of digital modulation techniques. These are;. Amplitude-Shift Keying (ASK). Frequency-Shift Keying (FSK). Phase-Shift Keying (PSK). All of these techniques vary a parameter of a sinusoid to represent the information which we wish to send. A sinusoid has three different parameters than can be varied. These are its
MODULATION. Modulation is the process whereby some characteristic of one wave is varied in accordance with some characteristic of another wave. The basic types of modulation are angular modulation (including the special cases of phase and frequency modulation) and amplitude modulation.
Angle Modulation: In the angle modulation, again there are two different types of modulations. 1. Frequency modulation. 2. Phase modulation. 1. Frequency Modulation: The process of carrier signal .. number of ways. In demodulation, we need PWM detector and its related circuitry for demodulating the PWM signal.
30 Sep 2014 The modulated signal is shown in the below figure, and its spectrum consists of the lower frequency band, upper frequency band and carrier frequency components. This type of modulation requires more power and greater bandwidth; filtering is very difficult. Amplitude modulation is used in computer
"Modulation is defined as the precess by which some characteristics, usually amplitude, frequency or phase, of a carrier is varied in accordance with to the band between 120KHz and 130KHz, Then both programs gave still 10KHz bandwidth and the listener can (by band selection) retrieve the program of his own choice.

Modulation. – process of changing one of the characteristic of an analog signal (typically a sinewave) based on the information in a digital signal. • sinewave is can be represented by varying any of the three. • application: transmission of digital data over telephone wire (modem). Types of Digital-to-Analog. Modulation
Chapter 7: Pulse Modulation. ? Basic concepts. ? Modulation: a process by which a property of a parameter of a signal is varied in proportional to a second (given) signal . We use modulation technique to alter signals in time and frequency to accomplish desired objectives. ? Analog or continuous-wave (CW) modulation:.
