Study Notes
Measurements and Rectifiers
- Resistance cannot be measured without a voltmeter.
- Rectifiers convert Alternating Current (AC) to Direct Current (DC).
Filters and Clippers
- The smaller the bandwidth, the better the quality.
- Clipping of clippers occurs when the input signal exceeds a certain voltage, which depends on the quality of the clipper.
- Shift of clampers occurs when the input signal exceeds a certain voltage, which depends on the quality of the clamper.
- Clampers change the position of the wave up and down.
- In bandpass filters, the gain (Av) is equal to 1/3.
- The cutoff frequency is obtained from the gain (Av).
Op-Amp Configurations
- In negative feedback op-amp, the voltage at the non-inverting input (V+) is equal to the voltage at the inverting input (V-).
- In non-inverting amplifiers, the gain (Av) is equal to Rf/R.
- To achieve a gain of 6 in a non-inverting amplifier, R and Rf should be 2 and 20, respectively.
Clippers and Ripple Factor
- The ripple factor is inversely proportional to the frequency.
- Batteries do not affect the clipper.
Clipping and Filtering
- A 5-shift of clampers occurs when the input voltage is 10V - 5V, which depends on the quality of the clampers.
Wave Shaping
- 6 clampers can change the position of the wave up and down, which is a function of time (t).
cutoff Frequency
- The cutoff frequency can be obtained from the gain (Av) as a function of time (t).
Bandpass Filter
- In a bandpass filter, the gain (Av) is equal to 1/3, and the phase is 90 degrees.
Negative Feedback Op-Amp
- In a negative feedback op-amp, the voltage at the non-inverting input (V+) is equal to the voltage at the inverting input (V-), and the output voltage to input voltage ratio (Vo/Vi) is equal to the resistance ratio (Rc/R1).
Lowpass Filter
- In a lowpass filter, the output voltage (Vo) proceeds the input voltage (Vi) as a function of frequency (f).
Clipper Circuit
- The battery does not affect the clipper circuit, which is a function of frequency (f).
Ripple Factor
- The ripple factor is inversely proportional to the frequency, which means that as the frequency increases, the ripple factor decreases.
Non-Inverting Amplifier
- To achieve a gain (Av) of 6 in a non-inverting amplifier, the resistances R and Rf should be chosen respectively, such as 2 and 20, or 5 and 10, or 1 and 10, etc.
