RANCANG BANGUN MODUL OSILATOR JEMBATAN WIEN DAN OSILATOR PENGGESER FASA

Oscillator is a circuit that can generate an output signal in the absence of an input signal is given. Oscillator output can be sinusoidal shape, square, pulse, triangle and saw. Basically oscillator is a signal amplifier with positive feedback which the resonant circuit as a determinant of output frequency. Wien bridge oscillator (Wien Bridge oscillator) is used to generate frequencies without requiring the input signal with a frequency range of 5 Hz to about 1 MHz. At wien bridge oscillator is maintained in order to avoid phase shift, so that the phase angle fixed at 0 ° / 360 ° and can produce waves. Oscillator phase shifter has an inverting amplifier, and a feedback filter 180 ° phase shift of the frequency of oscillation. At the oscillation frequency, each filter produces a phase shift of each range of 60 ° in three RC circuit so that the entire filter forsoduksi 180 ° phase shift. This makes the amount of phase shift of 0 ° or 360 ° which can generate waveforms. Benefits of this report is to understand, to understand and to know the workings of the tool created. Suggestions for this report is to consider each value components used in the circuit because each component values could have an effect on the outcome. Based on the measurement results obtained wien bridge oscillator frequency of 2.29 KHz and phase shifter oscillator frequency of 1.99 KHz.
