You are asked to build a digital logic circuit for a security alarm system. the system has four motion sensors which indicate the presence of an intruder. each individual motion sensor should be able to trigger an alarm. the system should be completely disabled via a master switch. in addition, the siren, the lights and the automated call to the security company should have separate enable switches. the inputs and outputs are specified as follows: inputs: s1, s2, s3, s4 : motion sensors (0 = no intrusion detected, 1 = intrusion detected)m : master switch (0 = security system disabled, 1 = security system enabled)a : siren enable switch (0 = siren disabled, 1 = siren enabled)l : light enable switch (0 = flashing light disabled, 1 = flashing light enabled)p : phone call enable switch (0 = call disabled, 1 = call enabled)outputs: b : buzzing sirenf : flashing lightc : call boxdraw the logic circuit diagram of the digital logic using multi-input and/or/not gates.
