Waveforms and wave generators: blocking oscillator.

BLOCKING OSCILLATOR The BLOCKING OSCILLATOR is a special type of wave generator used to produce a narrow pulse, or trigger. Blocking oscillators have many uses, most of which are concerned with the timing of some other circuit. They can be used as frequency dividers or counter circuits and for switching other circuits on and off […]

Oscillators: pulsed oscillators, harmonics and frequency multiplication.

PULSED OSCILLATORS A sinusoidal (sine-wave) oscillator is one that will produce output pulses at a predetermined frequency for an indefinite period of time; that is, it operates continuously. Many electronic circuits in equipment such as radar require that an oscillator be turned on for a specific period of time and that it remain in an […]

ANSWERS TO QUESTIONS and SUMMARY of OSCILLATORS.

SUMMARY This chapter has presented information on oscillators. The information that follows summarizes the important points of this chapter. WAVE GENERATORS can be classified according to the SINUSOIDAL or NONSINUSOIDAL waveforms produced. SINUSOIDAL WAVE GENERATORS (oscillators) produce a sine wave of constant amplitude and frequency. There are three ways to control the frequency of sine-wave […]

Oscillators: crystal oscillators

CRYSTAL OSCILLATORS Crystal oscillators are those in which a specially-cut crystal controls the frequency. CRYSTAL- CONTROLLED OSCILLATORS are the standard means used for maintaining the frequency of radio transmitting stations within their assigned frequency limits. A crystal-controlled oscillator is usually used to produce an output which is highly stable and at a very precise frequency. […]
