Sweep Frequency Generator – Block Diagram and its Workings

Sweep Frequency Generator – Block Diagram and its Workings: A Sweep Frequency Generator is a special type of signal generator which generates a sinusoidal output whose frequency is automatically varied or swept between two selected frequencies. One com¬≠plete cycle of the frequency variation is called a sweep. The rate at which the frequency is varied can …

Miller Sweep Circuit and Miller Bootstrap Sweep Circuit

Miller Sweep Circuit and Miller Bootstrap Sweep Circuit: The basic R-C sweep circuit is shown in Fig. 30.134, in which opening of switch S provides sweep voltage, as already explained earlier. The waveform generated by this basic circuit is not exactly linear, even if the ratio of sweep voltage Vs and the supply voltage V …

Sawtooth Voltage Generator Circuit Diagram and Waveforms

Sawtooth Voltage Generator Circuit Diagram and Waveforms: Figure 30.129 represents a basic sawtooth voltage generator. Switch S periodically changes its position from point 1 to point 2 (although a mechanical switch is shown in the circuit, the switching action is actually performed electronically by means of a separate circuit not shown here). The switching action …

Methods of Sweep Voltage Generation

Methods of Sweep Voltage Generation: It is not possible to achieve precise linearity in sweep voltages by electronic means, various methods of sweep voltage generation are enumerated below. 1. Exponential Charging: In this method of time-base waveform generation, a capacitor is charged exponentially through a resistor from a constant voltage source to a voltage quite …

Time Base Generator – Working Principle and Types

Time Base Generator – Working Principle and Types: Time base is an axis, normally X-axis, that is used to represent time so that variations of quantities such as voltages, currents etc., or their waveforms can be plotted w.r.t. time. Most of the CRO applications involve measurement or display of a quantity which varies with respect …

Peak to Peak Detector – Working Principle and Applications

Peak to Peak Detector – Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal. The same circuit with a small-signal diode is known as a peak detector. Typically, peak detectors operate at frequencies that are much higher than 50 …

What is Comparator in Electronics? – Classification and Applications

What is Comparator in Electronics? – Classification and Applications A circuit used to mark the instant when an arbitrary waveform attains some particular reference level is called a comparator. The clipping circuits can also be used to perform the operation of comparison. In this case the circuits become elements of a comparison system. The only …
