1		The IC balanced modulator can work at carrier frequencies up to approximately 100 MHz.


2		The IC is one of the most versatile circuits available for communication applications.


3		Analog are often used to generate DSB signals.


4		In large-scale integrated circuits in which complete receivers are put on a single silicon chip, the circuitry is likely to be implemented with .


5		The simplest and most widely used method of generating signals is the filter method.


6		One SSB transmitter sideband selection method is to provide carrier oscillator frequencies.


7		The phasing method of SSB generation uses a(n) technique that causes one of the sidebands to be canceled out.


8		A phase shifter is usually a(n) network that causes the output to either lead or lag the input by ninety degrees.


9		The output of a phasing detector is a(n) SSB and must be applied to a linear RF amplifier before being applied to the transmitting antenna.


10		The balanced modulator is called a(n) detector because it is used to recover the modulating signal rather than generate a carrier that will transmit it.


11		The modulation index is the of the modulating signal amplitude to the carrier amplitude.


12		To produce AM, a carrier and modulating signals are and applied to a nonlinear device.


13		Modulation is a(n) process.


14		A differential amplifier modulator makes an excellent modulator.


15		A major disadvantage of modulators is the need for a modulation transformer.
