... in CE configure...
as Vo=Vcc-Ic Rc now as Vcc is consistent. v can say Vo is directly proportional 2 (-Ic Rc) so now when the base voltage is increased Ib will inc. thus, Ic will inc. cuz Ic=beta Ib thus Ic Rc drop increases... as Vo is prop 2 -Ic Rc thus, Vo will decrease...thus d curve for d +ve half cycle in which Ib is increasing drawn in 180 deg phase showing Vo is dec. n vice versa 4 -ve half cycle...
now in CC...
as d o/p is taken from emitter... Vo= Ie Re so der's no -ve sign..n for d +ve cycle Ie will increase leakage current) as der's no-ve sign it'll b in phase wid i/p..hence no phase shift as leakage current doesn't increase so much thus, dis o/p voltage Ie Re doesnt inc much thus, d o/p doesn't amplify much thus dis configure known as emiter follower...
now in CB,...
d I/P is applied at emitter n o/p is taken from collector... so, 4 d +ve half cycle d Eb junc will b more FB thus causing incr. in Ib n thus, in Ic... so inc. in Ic causes inc. in o/p voltage..n during -ve half cycle d junc will b less FB so o/p voltage will b decreasing..hence der's no phase shift...

What is the phase and phase shift in Integrator and Differentiator?

Use of single phase and three phase variac in electrical engineering?
single phase variac can give 0-270 voltage in ac forms. So it is used to know the voltage in any circuit.
When an alternating voltage is applied to a purely resistive circuit the A voltage lags the current B the voltage leads the current Ccurrent leads the voltage Dcurrent is in phase with the voltage?
'A' and 'C' are saying exactly the same thing. The correct choice is 'D'. The complex impedance of a purely resistive circuit is purely real. Since there is no reactance, there is no phase shift, so the power factor is ' 1 ', KVA = KW, KVAR = 0, etc.
What is the meaning of transformer vector group YNa0d1?
The critical information here is bolded, as follows: YNa0d1.The upper-case Y indicates that the higher-voltage windings are connected in wye (or 'star'). The upper case letter N indicates an accessible neutral connection on the high-voltage side.The lower-case 'a0' indicates an autotransformerwith an angular displacement of 0 degrees.The lower-case d indicates that an auxiliary lower-voltage winding connected in delta (or 'mesh').The numeral 1 is a multiplier of 30 degrees, and indicates the transformer connection's angular displacement(or 'phase displacement'). Angular displacement is expressed in multiples of 30 degrees, starting from 0 degrees.So this is a wye-connected autotransformer having an angular displacement of 0 degrees with a delta-connected auxiliary winding having an angular displacement of 30 degrees.
Why shift register are considered basic memory devices?
Shift registers contain multiple "flip flops" that can be set to represent a bit value (0 or 1). These values can be retrieved later and so the registers can function as memory.
What is the phase and phase shift in Integrator and Differentiator?
phase shift in integrator is 180 degrees and phase shift in differentiator is 0 degrees
Y12sinx 3.14 What is the amplitude period and phase shift?

What is the difference between analog phase shifter and digital phase shifter?
An analog phase shifter provides a phase shift with a varying control voltage. A digital phase shifter switches among phase states to provide discrete phase shifts. the more bits there are, the smaller the quantization/digitization error. For example, 1 bit phase shifter provides a phase shift of 0 and 180°, or 0 and 90°. 2 bit phase shifter provides a phase shift of 0, 90°, 180° and 270°. 3 bit phase shifter provides a phase shift of 0, 45°, 90°, 135°, 180°, 225°, 270°, 315°, 360°.
A series RC circuit will have a phase shift between 0 and 90 degrees?
If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.

When light enters from denser medium to rare medium what happens to its phase change?
When light enters from a denser medium to a rarer medium, the phase change it experiences is a shift towards a longer wavelength, known as refraction. This shift in phase is due to the change in the speed of light as it travels through the different mediums.
What is the phase constant 0 and how does it impact the behavior of the system?
The phase constant, denoted as 0, represents the initial phase angle of a sinusoidal wave. It determines the starting point of the wave and affects how the wave behaves over time. Changes in the phase constant can shift the wave's position in time and alter its relationship with other waves in a system.

Difference between absolute PSK and differential PSK?
In abs. PSK only instant phase for the incoming bits are considered. For DPSK, the difference between previous phase and the present phase is considered. Example: If BPSK is used, then for 0 if phase if pi and for 1 it is 0, then for abs. BPSK the phase states for the bit stream 1010 will be 0,pi,0,pi for DPSK, we assume initial phase is zero and a rule that , if incoming bit is zero, then phase difference is 0 and if it is 1 then, phase difference is pi. So, phase difference will be--pi,0,pi,0 Instant phase will be, pi,pi,0,0....Easy!!
Does cancellation law hold in a ring?
When the ring, R, is an integral domain. That is, when R has no zero divisors. Consider: ab=cb => ab-cb=0 => (a-c)b=0 Then because R has no zero divisors we have: a-c=0 => a=c
