Waveforms: Types, Characteristics, Generation, and Applications

Which waveform is described as a smooth, repetitive oscillation commonly seen in audio signals and AC power?

• Sine wave

• Square wave

• Triangle wave

• Sawtooth wave

• Pulse wave

A waveform that alternates sharply between high and low levels is primarily used in which area?

• Analog audio amplification

• Digital signals and timing circuits

• Mechanical vibration analysis

• Power factor correction

• Thermal sensing

Which waveform rises linearly and falls linearly, forming a triangular shape often used in synthesizers?

• Square wave

• Triangle wave

• Sawtooth wave

• Pulse wave

• Complex wave

Which waveform has a gradual rise and sharp drop (or vice versa) and is common in sound synthesis and display scanning?

• Sine wave

• Square wave

• Triangle wave

• Sawtooth wave

• Pulse wave

What distinguishes a pulse wave from a square wave according to its definition in electronics?

• It has a sinusoidal shape

• It uses variable width for its high state (duty cycle)

• It contains no high state

• It has a constant analog amplitude

• It is always low frequency

Which key characteristic is defined as the number of cycles per second of a waveform?

• Period (T)

• Frequency (f)

• Amplitude

• Phase

• Duty cycle

Period (T) refers to which of the following?

• The shift of a waveform relative to a reference

• The time to complete one cycle

• The peak voltage only

• The average power

• The slope during rise time

Amplitude is best described as:

• The phase angle of the waveform

• The number of cycles per second

• The peak value of voltage or current

• The DC offset of a signal

• The time from low to high

Phase in a waveform context refers to:

• Frequency stability over time

• The shift in the waveform relative to a reference point

• The RMS value of the signal

• Only the initial value at t=0

• Duty cycle percentage

Which instrument can produce different waveforms such as sine, square, and triangle primarily for testing and signal processing?

• Crystal oscillator

• Function generator

• Spectrum analyzer

• Power inverter

• Thermocouple
