Tuned Circuits in Bandpass Amplifiers, a small-signal amplifier, the desired overall gain (transfer) function should provide a magnitude versus frequency response such as that shown in Figure 7.1. The peak-magnitude response occurs at what is labeled the ., ... By definition, the frequencies where the magnitude is ‘down’ from the peak v

鄙视

Simple Bandpass Amplifiers,capacitor combinations in overall negative or positive feedback configurations. These active R-C configurations are a most interesting study in themselves. In this section, only two basic types are introduced to illustrate the realization techniques.

Basic Electronic Oscillators,s, or connections in the amplifier, a feedback signal proportional to the output is produced. If this feedback signal is in phase with the input, a regenerative situation exists, and if the magnitude of the feedback is large enough, an unstable circuit is obtained. That is, if any input, including n

VICT

Electronic Oscillators with Bias-Shift Limiting,ct that although the basic differential equation which describes the oscillator has the same form as that encountered in the last chapter, there is now a new limiting phenomenon. The essential limiting of the growth of oscillatory buildup is due to the shift of the virtual or dynamic operating point

outrage

Analog Multipliers, Mixers and Modulators, frequency spectrum from one passband to another. This is often referred to by the term, mixing. In the early days of electronics, before the availability of reliable analog multipliers, two signals were combined (mixed) in a nonlinear device and the mixing (beating) of the two signals produced sum
