Difference Between Frequency Modulation and Amplitude Modulation: The Difference Between Frequency Modulation and Amplitude Modulation are discussed below The frequency modulation (FM) has the following advantages over the amplitude modulation…
Single Sideband Modulation (SSB): Single Sideband Modulation (SSB) can he obtained by passing the output of a carrier suppressor (product modulator) through filter circuits that are selective to transmit one…
Emitter Modulation - Circuit Diagram and its Operation: The circuit for emitter modulation is shown in Fig. 22.29. It is essentially a CE amplifier. The carrier signal from a crystal…
Collector Modulation Circuit - Working, Advantages and Disadvantages: This is very popular method for AM generation. The circuit diagram for collector modulation is shown in Fig. 22.26. Here, the transistor…
Time Base Generator - Working Principle and Types: Time base is an axis, normally X-axis, that is used to represent time so that variations of quantities such as voltages, currents…
Generation of Frequency Modulation: The Generation of Frequency Modulation system is a variable output frequency, with the variation proportional to the instantaneous amplitude of the modulating voltage. The subsidiary requirements…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates…
Need of Modulation in Communication System: Until the process of superimposing a low-frequency (long-wave) voice information component on a high-frequency (short-wave) carrier signal was perfected, the most widely used form…
