Time-Varying Signals

In this lab a voltage divider is used by two resistors. Output voltage is a linear function of input voltage as shown in Fig 1.

Figure 1: Time-Varying Signals

Vout = [R2 / (R1 + R2)]*Vin , When R1 = R2 then Vout = (1/2)*Vin
This circuit never change the shape of input wave. the output voltage is a coefficient of the input voltage. Input signals sinusoidal, triangle, and square are connected to the circuit, and output voltages are again sinusoidal, triangle, and square. Only the output voltages amplitude are half of input voltage amplitudes.
Frequency of input and output voltages are the same, and it calculates with oscilloscope. According to time division on oscilloscope and f = 1/T , frequency is measured.

Vin = 2 volts for the sinusoidal, triangle, and square waves, and Vout = 1 volt. f = 1000 Hz
