Design a regulated powersupply that will supply 1 A output current with a DC voltage outputof +5V and -12V with a ripple voltage of 0.01 V peak to peak. The design should provide output short circuit protection. Your design should include a circuit schematic and provide complete specifications for the transformer, rectifier and all components used in the design.Your design description should show all calculations you have madeto size the components and provide all justifications why you have chosen the design and component specifications.
The amplitudes of two signals X and Y have joint pdf: fXY (x,y) = e^(-x/2)*y*e^(-y^2) for x>0 , y>0. (a) Find the joint CDF (b) Find P [sqrt(x) > y] (c) Find the marginal PDFs (d) Determine if X and Y are independent.
a digital channel is described by 16 QAM, the data rate is 50 Mbps, the bandwidth is 200 MHz, the power is 1 W, and the received noise level is 50 mW. Resolve for SNR, Baud Rate and the Max theoretical bit rate for the channel.
A single, common-anode, 7-segment LED is connected to the Arduino Connector J1 through current-limiting resistors. The diagram in Figure 1 shows the mapping of the pins of the connector to the pins of the 7-segment.
Design a BJT differential pair amplifier (balanced in, unbalanced out) that provides 20 dB differential gain and 40 dB CMRR. Assume b = 100, ro = 50 KW. Use dual dc power supplies +Vcc and -Vee.
