Analog Multipliers, Mixers and Modulators,tor is the presence of the square-law term of the device transfer characteristic which leads to the (cross) product of the two signals. With a more complicated circuit, easily realizable in IC form, the multiplication can be achieved directly.

Tuned Circuits in Bandpass Amplifiers,alue by a given amount are called the . edges, and the interval between these is the . of the passband. Commonly, the bandedges are defined in terms of the −3. points and the bandwidth is then called the −3. bandwidth. These aspects are developed in greater detail in the next section.
