The equation y[n] - p y[n-1] = x[n] can be used to describe thevalue y[n] of a new investment by setting p = 1 + r/100 where r is the interest rate per period, expressed inpercent.
Find the transfer function of this system and determine whether itcan be both stable and causal.
A certain sawtooth generator has the following parameter values: Vin: 3v, R: 4.7kohm, C:0.001uf. Determine its peak-to-peak output voltage if the period is 10 us. What is the Vpp

You have a shortwave AM receiver (just an AM receiver that has the capability to receive signals in the FM frequency band) that receives an NBFM voice signal at some carrier frequency. You notice, however, that while the signal strength is maximiz..
Determine the turns required in each phase of a star connected alternator operating on an 11 kV 50 Hz system if it has a flux per pole of 0.38 Wb, pitch factor of 0.95 and breadth factor of 0.98
However, for short-time operation, a delta connection can be used at the nominal wye voltage. Find the ratio between the power delivered to the same motor in the wye and delta connections.
A curve of radius 159 m is banked at an angle of 11°. An 810-kg car negotiates the curve at 93 km/h without skidding. Neglect the effects of air drag and rolling friction. Find the normal force exerted by the pavement on the tires.
