- Waveform: Triangle wave Frequency: 5000 Hz Duty Cycle: 40% Amplitude: 8 Vp On the oscilloscope, set the timebase to 100 μs/Div. Now run the simulation and measure the rise time and fall time of the triangle wave in V/100 μs. Are these values consistent with a 40% duty cycle? I am trying to calculate V/100us. (T2−T1) rise=32.474uS (T2−T1) fall=47.755uS Minimum Voltage (V_min): 786.026 mV = 0.786026 V Maximum Voltage (V_max): 7.206 V Slope(rise) =6.419974/32.474×10^6 = 197,579.76,V/s *1,s/100,μs =197,579.76,V/100us I am checking the answer and I am concerned for V/100us =197,579.76,V/100us is to high? Please help me verify the answer for V/100us is correct. (I just need the calculations from my measurments) any insight is appreciated I did not post the pics of my virtual oscilliscope.arrow_forwardConnect the function generator and the scope, as shown in the same example. Set the function generator as follows: Waveform: Triangle wave Frequency: 5000 Hz Duty Cycle: 40% Amplitude: 8 Vp On the oscilloscope, set the timebase to 100 μs/Div. Now run the simulation and measure the rise time and fall time of the triangle wave in V/100 μs. Are these values consistent with a 40% duty cycle? How do I answer this question? what is V/100us?arrow_forwardhelp on this question about noise figure?arrow_forward
- A given FM broadcast receiver has an equivalent noise bandwidth of 200 kHz, a baseband bandwidth of 15 kHz, and a noise figure of 6 dB. What should be the received RF signal power so that the variable thermal noise is less than 60 dBm0, if the 800 Hz test signal and 0 dBm0 level produces a frequency deviation of 75 kHz?arrow_forwardplease redraw the equivalent circuit to make it look more realistic or correct anything that you see looking incorrect. this is the equivalent circuits for the transmission lines “Duhaney Park - WashingtonBoulevard” and “Washington Boulevard – Three Miles”.arrow_forwardAdd the following binary numbers: 1011 + 101, 1011 + 1101.arrow_forward
