Mixer has been connected to an rf signal with a frequency of fs 169.3 mhz and an lo with a frequency of fl 138.3 mhz. a spurious frequency of 953.8 mhz is observed on the spectrum analyzer. from the background section of the lab we know this frequency is a combination of harmonics of fs and f, that is m(fs) +-n(fl), where m and n are integers. what is the harmonic of fs required for this spur (i. e. what is the integer m)?

Four objects each with charge +2.0×10−7c are located at the corners of a square whose sides are 2.0 m long. part a what quantities can be determined using this information? check all that apply. the electric force on a charged object placed at the center of the square. the mass of each object. the total electric potential energy of the system consisting of the four charged objects. part b find the electric force on a charged object placed at the center of the square.
