The output level of a switch in correspondence to the logic level will be as follows in table 2: Logic Level Output Level LO 0V HI 5V Table 2: Logic and Voltage Levelġ2. 8 Bits Data Switches: Eight binary switches from SW0 - SW7 are available to provide binary input to the logic circuit. The logic level in correspondence to the input applied at the LED will be as follow in Table 1: Logic Level Input Level Display Light Up LO 2.3V ± 0.2V Red OPEN 0.8V - 2.3V No display (LED is OFF) Table 1: Input and Logic levelġ1. 8 Bits LED Display: Eight LEDs from 0 - 7 are available to test the state of the logic output. Universal Connector Fixed Holders: These are reserved fixed holders on the panel in order to be connected with various connectors. TTL logic will be used throughout in this manual. Mode Selector: Using mode selector switch the mode can be selected between TTL logic and CMOS logic. Pulser Switches: Two pulser switches (push buttons) A and B along with their ̅ and B ̅ are available to generate pulse as input. Amplitude Variable: A knob to vary the amplitude of the output square waveform. Frequency Range: A knob to select one of the frequency ranges which are as follows: a) 1Hz – 10Hz b) 10Hz – 100Hz c) 100Hz – 1kHz d) 1kHz – 10kHz e) 10kHz – 100kHz f) 100kHz – 1MHz 6. ![]() Frequency Variable: A knob to vary the frequency of the output square waveform. Variable Negative Power: A variable DC power supply with DC output from -3V to -15V, 500mA. Variable Positive Power: A variable DC power supply with DC output from 3V to 15V, 500mA. Power Switch: A switch to turn ON/OFF the logic trainer. The front panel is explained in detail below:įigure 1 Front Panel of Digital Training System ETS-5000Ĭomponents of ETS-5000 Trainer: 1. Figure 1-1 shows the front panel of ETS-5000 logic trainer. ![]() It is also ideally suited for developing, debugging, integrating and testing digital systems. It is designed to provide all the basic tools necessary to conduct logic experiments. Logic trainer: ETS-5000 logic trainer is a low cost, high performance digital logic teaching system. In this experiment, both logic trainer and logic probe are introduced. Moreover, for testing of logic circuits GLP-1A logic probe would be used. To get familiar with the equiment that would be used in rest of the semester for the implementation and testing of logic circuitsĮQUIPMENT: Logic trainer, Logic probe THEORY: In this manual, all experiments would be performed on ETS-5000 logic trainer using low power TTL ICs. 11, Design and analysis of sequential circuitsĪppendix C: Guidelines on Preparing Lab Reportsħ4LS74 (Dual positive edge triggered D flip flop IC)ĮXPERIMENT # 1 INTRODUCTION TO LOGIC TRAINER & LOGIC PROBE OBJECTIVE: 10, Introduction to Logic WorksĮxperiment No. 8, Implementation of logic circuit using decoder & MUX ICsĮxperiment No. 7, Decoder, priority encoder, & multiplexerĮxperiment No. 5, The use of universal gates & mappingĮxperiment No. 2, Introduction to basic gates and troubleshootingĮxperiment No. 1, Introduction to logic trainer and logic probeĮxperiment No. DEPARTMENT OF ELECTRICAL ENGINEERING, FAST-NU, LAHOREĮxperiment No. ![]()
