They are essentially the same. You are using a capacitor to "short out" any AC while DC is unchanged.
A filter capacitor is used to filter line frequency and twice line frequency from a transformer rectifier combination.
A bypass cap is used on ICs and transistors to remove any high frequencies from a supply line as close to the IC or transistor pins as possible.
They are similar, but the bypass cap, while also removing line frequencies, also is used to remove higher frequency spikes from the supply that can cause ICs to malfunction. The spikes can come from other nearby ICs switching state, which causes transients in the supply line.
Bypass caps are usually 0.1µF 20 volts ceramic and are located as close as possible to the ICs, and you usually have one of these for each IC. Then you have one or a few larger caps, say 100µF 10 volt, per board. The 0.1µF ones remove the very high frequencies, and thus must be close to the ICs. The 100µF ones remove the lower frequencies.
But, you can call bypass caps "filter caps" if you want, there is a lot of overlap.
There are also "filter caps" that are used in low pass filters, so the terminology can be confusing.

What is the effect of bypass capacitor on frequency response?
Gain in a CE configuration of a BJT is collector resistance divided by emitter resistance, subject to the limit of hFe. The emitter bypass capacitor will have lower impedance at high frequency, so the gain will be higher at higher frequency, making this a high-pass amplifier.
What is the function of a bypass capacitor in an amplifier?
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
Why bypass capacitor of the second stage to disconnect to get the output?
we can use the Out Put Capacitor Ex Kvar
What is purpose of emmiter bypass capacitor in R-C coupled amplifier?
Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
Capacitor from emitter to ground in common emitter circuit is called?
The capacitor is called a bypass capacitor , it provides a low impedence path for AC emitter current to groun.

What is the use of capacitor in circuit?
to bypass current and charge and discharge current
What is the output resistance of common emitter amplifier with emitter resistor and without bypass capacitor?
Without a bypass capacitor it is just equal to Rc
What is use of capacitor Ce across emitter resistance?
It can be used as a feedback and to ground unwanted signals and frequencies
Why bypass capacitor is used in common emitter ampifier circuit?
If a bypass capacitor is used the voltage drop across emitter resistance is reduced which in turn increases the gain.....

Emitter bypass capacitor is a capacitor which provide low impedance to AC and high impedance to DC . AC is shunt then only DC appears on RC and volage gain increses.
Why we use blocking and by pass capacitor in CE amplifier?
As the DC component in the signals are not required to be amplified, rather not required at times. Thus a blocking capacitor blocks this DC component from.entering the amplifier. Bypass capacitors are used at the emitter end so that the AC signal reaching the emitter end does not alter the biasing required to maintain the Q-point. All the above happens using the basic characteristic of a capacitor, that it blocks DC and passes AC.

What is the emitter bypass capacitor?
The capacitor helps to keep the quiesent point fixed. During its operation it bypasses the ac component. If the ac also flows through this emitter link then as we know by parameter equations emitter current and ce voltage changes hence varying q point.
How capacitor bypass alternating current?
It passes AC through it and blocks DC
