1. Determine the appropriate value of frequency for a square wave generator (in Hz) to measure the time constant on an oscilloscope for a series R-C circuit with R = 47 ΚΩ and C= 0.1 uF.

7. A double beam oscilloscope displays 2 sine wave forms A and B. The time/cm switch is on 100 us/cm and the volt/cm switch is on 2V/cm.The width of each complete cycle is 5cm for both the waveforms. The height of waveforms A and B are 2 cm and 2.5 cm respectively. The distance between consecutive cross over of waveforms A and B is 0.5 cm .Determine (i) frequency (ii) peak and rms value of voltages (iii) phase difference.

An oscilloscope shows peak-to-peak amplitude of 8 cm for a measured sinusoidal voltage waveform with vertical sensitivity knob set to 4 V/cm. The average value of the voltage is:

Draw a sinusoidal waveform with a peak-to-peak voltage of 6 V and a frequency of 1kHz in an oscillogram showing the grid lines of an oscilloscope as shown below. Use 1V/div vertical division and 1ms/div horizontal division.
