You place an ac voltage signal of amplitude 1.4 v and with a frequency of 1400.0 hz, into the input of an oscilloscope.

a.) find the distance displayed on the screen of the oscilloscope for a full wave, if the sweep speed is adjusted to 119 �sec/div. (in divisions)

b.) if the vertical gain is set to 0.40 v/div, how many divisions will the wave span from peak-to-peak of the wave? (in divisions)

(a). The horizontal distance on the screen is 6 Div.

(b). The number of division from peak to peak is 7 Div.

Explanation:

Given that,

Amplitude = 1.4 V

Frequency = 1400.0 Hz

Vertical gain = 0.40 V/Div

Sweep speed

We need to calculate the period

Using formula of period of input voltage

Put the value into the formula

(a). We need to calculate the distance displayed on the screen of the oscilloscope for a full wave,

Here, v = sweep speed

Put the value into the formula

The horizontal distance on the screen is 6 Div.

(b). We need to calculate the peak to peak vertical amplitude of the wave

Using formula of amplitude

Put the value into the formula

We need to calculate the number of division from peak to peak

Using formula of division

Put the value into the formula

The number of division from peak to peak is 7 Div.

Hence, (a). The horizontal distance on the screen is 6 Div.

(b). The number of division from peak to peak is 7 Div.
