DUAL-DIODE LIMITER The last type of limiter to be discussed in this chapter is the DUAL-DIODE LIMITER, shown in figure 4-15, view (A). This limiter combines a parallel-negative limiter with negative bias (D1 and B1) and a parallel-positive limiter with positive bias (D2 and B2). Parts of both the positive and negative alternations are removed […]

Wave shaping: common-base transistor clamper, shaping circuits and composition of nonsinusoidal waves.
COMMON-BASE TRANSISTOR CLAMPER The common-base transistor clamper is similar to the dual diode limiter in figure 4-15, except for the addition of a transistor. In the previous clampers, we have clamped the output signal to a reference. In the transistor common-base clamper, we want to clamp the amplitude of the input to no more than […]

Waveforms and wave generators: time-base generators.
TIME-BASE GENERATORS Radar sets, oscilloscopes, and computer circuits all use sawtooth (voltage or current) waveforms. A sawtooth waveshape must have a linear rise. The sawtooth waveform is often used to produce a uniform, progressive movement of an electron beam across the face of an electrostatic cathode ray tube. This movement of the electron beam is […]

Answers to questions and summary of waveforms and wave generators.
SUMMARY This chapter has presented information on waveforms and wave generators. The information that follows summarizes the important points of this chapter. A waveform which undergoes a pattern of changes, returns to its original pattern, and repeats that same pattern of changes is called a PERIODIC waveform. Each completed pattern of a waveform is called […]
