AC SIGNALS: Th signals with a constant value of amplitude are called "Direct Current" (DC) signals. Here the current flowing through the circuit has a fixed value.  However, there are signals that have a time varying amplitude. These are called "Alternating Current" (AC) signals. Pure AC signals are centered at 0 voltage level. The most common ones are; sinusoidal , square and triangular waves. Sinusoidal waveform Va: peak voltage (max) Vpp: peak to peak voltage (difference of between max and min) Square waveform Triangular waveform The formula for sinusoidal wave is;      Sinusoidal: Vsinusoidal(t) = Va*sin(2*pi*(1/T)*t), where t is time variable. (Notice how voltage of sinusoidal is a function of time, t). Pi is pi (i don't know how to write 'pi'), the gradient which corresponds to 180 degree.      The important parameters are;      - T, Period : The duration for one cycle to finish. Unit is...

Truth Tables and Verilog Codes for one-bit Half Adder and Full Adder HALF ADDER By using half adder, you can design simple addition with the help of logic gates.   Half Adder 0+0 = 0 0+1 = 1 1+0 = 1 1+1 = 10 These are the least possible single-bit combinations. But the result for 1+1 is 10, the sum result must be re-written as a 2-bit output. Thus, the equations can be written as 0+0 = 00 0+1 = 01 1+0 = 01 1+1 = 10 The output ‘1’of ‘10’ is carry-out. ‘SUM’ is the normal output and ‘CARRY’ is the carry-out.

WHAT IS AN OP-AMP? An operational amplifier is a DC-coupled high-gain electronic voltage amplifier with a differantial input and, usually, a single-ended output. Let's design 2 types of Op-Amp circuit in Matlab Project. Op-Amplifier usually have 2 inputs and 1 output. (-) marked end is evolved, (+) marked end is not evolved. If you apply a signal to the (-) sign, you can get an output signal that is 180 degrees out of phase from the output as this tip is evolved. If you apply a signal to the (+) sign, there will be no change in your output signal, because this marked end is not evolved. The gain at low frequencies is usually large. Now let's examine the Non-Inverting Op-Amp: The using the formula to calculate the output voltage of a potential divider network, we can calculate the voltage gain (Av) of the Non-Inverting Amplifier as follows: Now let's examine the inverting Op-Amp: GUI DESIGN GUI DESIGN Let...
