A signal generator is a test equipment that produces electrical signals in waveforms, used in the design, testing, and servicing of electronic devices. The document discusses the purpose, requirements, types, and applications of signal generators, highlighting their stability in output frequency and amplitude control. Types include function generators, RF and microwave generators, and arbitrary waveform generators.

3. What is
Signal
Generator?
SignalGenerator
A signal generator is piece
of test equipment that
produces an
electrical signal in the
form of a wave.

4. A SIGNAL GENERATOR IS AN
ELECTRONIC DEVICE THAT
GENERATES REPEATING OR
NON-REPEATING
ELECTRONIC SIGNALS IN
EITHER THE ANALOG OR THE
DIGITAL DOMAIN.

5. Requirements of signal
generator
the requirements are common to all the types
1. The output frequency of signal generator should be
very stable
2. The amplitude of output signal of signal
generator should be controllable from low values to
relatively large values
3. The amplitude of output signal must be stable.

6. PURPOSE OF SIGNAL
GENERATOR
A common use is to test the response of circuits to a known input signal.
Most function generators allow you to generate sine, square or triangular AC
function signals.

7. Uses
Signal generators of all types are mostly used
in designing, manufacturing, servicing and repairing
electronic devices.

8. TYPES
Function generators
RF and microwave signal generators
Pitch generators
Arbitrary waveform generators
Digital pattern generators,and
Frequency generators.

9. The most basic signal created
from a signal generator is the
continuous wave (CW) signal, or
sine wave, which has no
modulation and is produced by a
basic signal source.
Varying the sine wave's
amplitude achieves AM and pulse
modulation. Varying the sine
wave's frequency or
phase generates FM and ΦM,
respectively.

10. Signal generator is a kind of equipment that
can provide all kinds of
frequency, waveform and output
electric signal.
Signal generator, also known as signal source
or oscillator, has a wide range
of applications in the field of production
practice and science and technology.
