Textbook Question
Chapter 18, Problem 2PA
You are working on a residential heat pump. The heat pump is connected to a 240-V, 60-Hz power line. The compressor has a current draw of 34 amperes when operating. The compressor has a power factor of 70%. The backup strip heat is rated at 10 kW. You need to know the amount of total current draw that will occur if the strip heat comes on while the compressor is operating.

Connect 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?
help on this question about noise figure?
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?
