Methods of Suppressing Unwanted Sidebands
Methods of Suppressing Unwanted Sidebands: As stated earlier, the three practical methods of SSB generation all use the balanced modulator to suppress the carrier, but each uses a different method…

Define Suppression of Carrier: Three main systems are employed for the generation of SSB; the filter method, the phase cancellation method and the "third method." They differ from one another…
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…
Amplitude Modulation Theory: In Amplitude Modulation Theory, the amplitude of a carrier signal is varied by the modulating voltage, whose frequency is invariably lower than that of the carrier. In…
Internal Noise in Communication System: Under the heading of Internal Noise in Communication System, we discuss noise created by any of the active or passive devices found in receivers. Such…
Temperature Control System: Before going to study the temperature control system, let us see the block diagram of microprocessor based process Temperature Control System. It is capable of controlling more…
Sample and Hold Circuit: Four basic sample and hold circuit are shown in Fig. 14.141. In these circuits a JFET is used as switch. During the sampling time the JFET…
DAC0830 Digital to Analog Converter: The DAC0830 Digital to Analog Converter is an advanced CMOS 8-bit DAC designed to interface directly with the 8080, 8048, 8085, Z80, and other popular…
