HW 1(1)

Design an encoding matrix with diodes and resistors to display a decimal number to on the seven-segment display. You have 10 switches (WO-W9) with one terminal connected to Vec. For decimal number 0, switch 0 (S0) is closed, for decimal number 1, switch 1 (S1) is closed etc. (Switches are on the vertical axis, S0 on top and the outputs are taken on the horizontal axis (Y0-Y6), with “a" on the left and "g" on the right. Note that (Y0-Y6) outputs are used as inputs to seven-segment display. Since these outputs cannot drive the seven segment display LEDS you may need additional bipolar transistors and resistors. The supply voltage is 5V and each LED needs a current of 20mA. Note that this is a design problem and the design is not unique. Do your best! f a a e

A It can be an analog signal. It compresses the data into minimum number of bits. It converts the signal into the original physical form, which was at the input of the transmitter. It does the coding for error correction. It allows the analog signal to transmit from the transmitter end to the receiver end. It produced after the whole process. It takes a physical input and converts it to an electrical signal. The received signal is demodulated as well as converted again from analog to digital.notni erli lo ini arli lo voeber edirsin.sm The resultant signal is once again…
