Assertion: frequency | /r/HasProperty | varied in waveform generators
Facets:
value: by changing the values of capacitances
type: MANNER
Source sentences:
text: However in waveform generators and other laboratory instruments, the frequency is varied by changing the values of Capacitances ( variable capacitors or adding stages by switching) , and than the output is amplified to raise the amplitude of waveform i.e Voltage level of waveform at desired level (which is limited to the scope and size of instrument.)
