Question

c. Determine the minimum time/division sensitivity for an oscilloscope that is to be used to 

investigate a 50 MHz waveform.Assume that the time base magnifier expands the horizontal 

display by a factor of 5.

d. Determine the displayed rise time when a pulse waveform with a rise time of 21 ns is applied to 

an oscilloscope that has an upper cutoff frequency of (a) 20 MHz and (b) 50MHz.

e. A 1kHz triangular wave with a peak amplitude of 10 V is applied to the vertical deflecting 

plates of a CRT. A 1kHz sawtooth wave with a peak amplitude of 20 V is applied to the 

horizontal deflecting plates. The CRT has a vertical deflection sensitivity of 0.4cm/V,and a 

horizontal deflection sensitivity of 0.25cm/V.Assuming that the two inputs are synchronised, 

determine the waveform displayed on the screen.

f. A digital storage oscilloscope has a sampling rate of 100MS/s. Determine the number 

of samples taken during one cycle of a 3MHz sine wave, and during a 15µs pulse. Also, 

estimate the maximum time period of a glitch that might be missed by the sampling 
process.​
