4 what is the name of the circuit that adds a positive or negative dc voltage to an input sine wave?
This DC voltage is called the DC offset. Any decent signal generator will be able to add DC offset to the signal it generates. If you don't have one, simply connect a DC voltage to your signal.
Is clock pulse an ac or DC signal?
It is called ( pulsed DC ).
Can you step up or step down the DC voltage by a transformer?
You need alternating current for a transformer, for DC you would have to interrupt the power supply to make it effectively DC pulses.
What is the purpose of dc power?
theperpose of a power supply is to step up or step down an ac voltage to a desired dc value
What is the unit step signal?
seasning

Is signal ac or dc?
ac
How does frequency affect amplitude?
we use dc supply for amplifcation and dc have no frequincy. we amplify just signal curent or signal voltage.
Why amplification of ac signal is easier than a dc signal?
The Amplification is much high during acmode because of transister conducts boththe Half cycles.But in DC the transister conducts only in positive half cycles.So the Amplification of AC signal greater than DC signal.
CAN YOU STEP DOWN 36 volt dc to 12 volt dc using batteries?
can ou step down 36 volts dc to 12 volt dc using batteries
What is the operation of a rectifier?
The operation of a rectifier is to conver a AC signal to a pulsating DC signal
What is DC chopper?
chopper use a ststeing perpose..... dc means direct current that is low voltage
Is unit step signal is bounded or unbounded?
bounded signal
What is a direct current input signal?
DC current
What is static signal?
signal which remains constant over a certian interval of time.e.g dc voltage
