Essentially all RC circiuts filter of time. Annother application is.....
setting tyhe frequency response of FM radios(filtering). In the
FM radio business one talks about a 75 micro-secondfilter.
How about the detector of an AM receiver following the diode, and the.....
de-emphasis network in an FM receiver; loop filters inphase-locked loops;
phase-shift network of an RC oscillator
speaker crossover networks, assuming that the speaker is a resistor.......
filter concepts and the general action of the components
made them much more receptive to the analysis later.
2. A small factory is supplied by a three phase circuit with a phase.....
voltage of 240 V (rms). The load at the factory is a balanced delta.
and absorps a total of 30 kVA with a power factor of 0.95 (lagging).
Model 267-1/2 - Card Mounted EIA-530 to RS-232 Interface Converter.....
Due to proximity between circuits of a double circuit HV line.....
over mutual inductive and capacitive linkages there occur
considerable impacts between these circuits. This is reflected
oscillators: pierce crystal oscillator..... capacitor is a blocking.....
capacitor in series with the crystal to protect it from d-c plate
voltage. This capacitor is not always used. Bias is provided in the
cathode circuit by r2 and c2 and in the grid circuit by R and the
capacitance of the crystal holder
ratio detector: A single resistor R1 is used in place of the former R1.....
and R2 and this resistor is shunted by another capacitor C6. This last
combination R1C6, forms a long time constant circuit......
In other words, this RC circuit tends to maintain a constant voltage
between points b and e, as if it were a battery connected across theses
two points
AVC (AGC) automatic volume control, automatic gain control:.....
... voltage consistes of two components, a d-c component and the
intellegence, or audio, component. If this voltage were applied directly
to the AVC- controlled tubes, the gain would vary at an audio rate,
causing severe distortion... so this audi component must be filtered out
and an RC filter is used. Capacitor must have a low reactance compared
to R at the lowest modulating frequency.
in series-fed circuits Rc are decoupling filters
phase modulator /variable phase shiting network.: .. the simplest phase.....
shifting network is an RC network in which either C or R is variable.
audio-correction network: resistor and capacitor froming a voltage-.....
dividing network. At low audio frequencies the reactance of C is high
compared to the resistance of R, so the audio signal applied to the
phase modulator is essentially the same as the output signal from the
audio amplifier.

RC couple amplifier: at low frequencies a change in frequency of only a.....
few hertz will cause noticeable change in the amplifier output voltage.
