This is another widely used circuit because it s easy to implement and very stable.
Variable frequency sine wave oscillator. Martin fischman by at ipa e. The higher the basic frequency of the vfo the wider the tuning range you can achieve. A pure sine wave has only a single or fundamental frequency ideally no harmonics are present. Make offer kenwood vfo 820 remote variable frequency oscillator.
Kenwood vfo 820 remote variable frequency oscillator. 2 1967 2 sheets sheet 2 lagging current phase angle phase angle tuned o circuit iurrent leading phase angle fig. One sinewave is available from u2a as shown technically this is the cosine delayed by 90 with respect to the sine output and another can be taken. Considering the size of most ham bands a vfo needs a tuning range of at least 0 5 mhz.
The state variable filter based oscillator shown above is also known as a quadrature oscillator because it produces two sinewaves in quadrature they are exactly 90 apart sine and cosine. Its useful frequency range is approximately 100 khz to 40 mhz. Frequency conversion is covered in chapter 11. Sine wave oscillators are used as references or test waveforms by many circuits.
A variable frequency oscillator vfo in electronics is an oscillator whose frequency can be tuned i e varied over some range. You didn t specify the frequency 100hz or 100mhz or how much the frequency had to be varied 0 01 or 1000 or whether the frequency had to be varied by a voltage or a physical knob. A one transistor fet hartley oscillator is hard to beat for cheap. The output is a sine wave with a slight distortion.
The resonant point of the network. Variable frequency sine wave oscillator filed feb. Y 7 1968 m. This is done by adding the vfo to a high frequency crystal oscillator signal and then filtering out the sum frequency.
Purity of sine wave and stability matters too. For the eelctronic circuit design of a sine wave oscillator the bridge can be used within the feedback loop and the circuit oscillates at the balance point i e. Isotemp 143 141 10mhz ocxo 5vdc. 2pcs cts 1960017 10mhz 5v sine wave ocxo crystal oscillator.
Thus a sine wave may be the input to a device or circuit with the output harmonics measured to determine the amount of distortion. Hp hewlett packard 201 audio oscillator 115 130 volt. It is a necessary component in any tunable radio receiver or transmitter that works by the superheterodyne principle and controls the frequency to which the apparatus is tuned. Variable frequency sine wave oscillator 2 sheets sheet 1 may 7 1968 filed feb.
